  • Updating Textures on Runtime in OpenSceneGraph

    - by Abhishek Bansal
    I am working on a project in which i am required to capture frames from external device video and render them on openSceneGraph Node. I am also using GLSL shaders. But i dont know how to update textures on runtime. For other uniforms we need to make callbacks but do we also need to make callbacks for samplers in glsl and openSceneGraph ? My code looks like this. All i am getting right now is a black window. osg::ref_ptr<osg::Geometry> pictureQuad = osg::createTexturedQuadGeometry(osg::Vec3(0.0f,0.0f,0.0f), osg::Vec3(_deviceNameToImageFrameMap[deviceName].frame->s(),0.0f,0.0f), osg::Vec3(0.0f,0.0f,_deviceNameToImageFrameMap[deviceName].frame->t()), 0.0f, 1.0f,_deviceNameToImageFrameMap[deviceName].frame->s(), _deviceNameToImageFrameMap[deviceName].frame->t()); //creating texture and setting up parameters for video frame osg::ref_ptr<osg::TextureRectangle> myTex= new osg::TextureRectangle(_deviceNameToImageFrameMap[deviceName].frame.get()); myTex->setFilter(osg::Texture::MIN_FILTER,osg::Texture::LINEAR); myTex->setFilter(osg::Texture::MAG_FILTER,osg::Texture::LINEAR); myTex->setWrap(osg::Texture::WRAP_S, osg::Texture::CLAMP_TO_EDGE); myTex->setWrap(osg::Texture::WRAP_T, osg::Texture::CLAMP_TO_EDGE); _videoSourceNameToNodeMap[sourceName].geode = new osg::Geode(); _videoSourceNameToNodeMap[sourceName].geode->setDataVariance(osg::Object::DYNAMIC); _videoSourceNameToNodeMap[sourceName].geode->addDrawable(pictureQuad.get()); //apply texture to node _videoSourceNameToNodeMap[sourceName].geode->getOrCreateStateSet()->setTextureAttributeAndModes(0, myTex.get(), osg::StateAttribute::ON); _videoSourceNameToNodeMap[sourceName].geode->getOrCreateStateSet()->setMode(GL_DEPTH_TEST, osg::StateAttribute::OFF); _videoSourceNameToNodeMap[sourceName].geode->setDataVariance(osg::Object::DYNAMIC); //Set uniform sampler osg::Uniform* srcFrame = new osg::Uniform( osg::Uniform::SAMPLER_2D, "srcFrame" ); srcFrame->set(0); //Set Uniform Alpha osg::Uniform* alpha = new osg::Uniform( osg::Uniform::FLOAT, "alpha" ); alpha->set(.5f); alpha->setUpdateCallback(new ExampleCallback()); //Enable blending _videoSourceNameToNodeMap[sourceName].geode->getOrCreateStateSet()->setMode( GL_BLEND, osg::StateAttribute::ON); //Adding blend function to node osg::BlendFunc *bf = new osg::BlendFunc(); bf->setFunction(GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA); _videoSourceNameToNodeMap[sourceName].geode->getOrCreateStateSet()->setAttributeAndModes(bf); //apply shader to quad _videoSourceNameToNodeMap[sourceName].geode->getOrCreateStateSet()->setAttributeAndModes(program, osg::StateAttribute::ON); //add Uniform to shader _videoSourceNameToNodeMap[sourceName].geode->getOrCreateStateSet()->addUniform( srcFrame ); _videoSourceNameToNodeMap[sourceName].geode->getOrCreateStateSet()->addUniform( alpha );

  • Variable reference in a Groovy GString

    - by Maurits Rijk
    From the book "Groovy and Grails recipes" I'm using the following code snippet: String HelloLanguage = "def hello(language) {return \"Hello $language\"}" However, I get a compiler error "You attempted to reference a variable in the binding or an instance variable from a static context." because language can't be bound. What is wrong?

  • URL Controller Mapping Strategies (PHP)

    - by sunwukung
    This is kind of an academic question, so feel free to exit now. I've had a dig through Stack for threads pertaining to URL/Controller mapping in MVC frameworks - in particular this one: http://stackoverflow.com/questions/125677/php-application-url-routing So far, I can ascertain two practices: 1: dynamic mapping through parsing the URL string (exploded on '/') 2: pattern matching matching url to config file containing available routes I wanted to get some feedback (or links to some other threads/articles) from folks regarding their views on how best to approach this task.

  • C# MultiThread Safe Class Design

    - by Robert
    I'm trying to designing a class and I'm having issues with accessing some of the nested fields and I have some concerns with how multithread safe the whole design is. I would like to know if anyone has a better idea of how this should be designed or if any changes that should be made? using System; using System.Collections; namespace SystemClass { public class Program { static void Main(string[] args) { System system = new System(); //Seems like an awkward way to access all the members dynamic deviceInstance = (((DeviceType)((DeviceGroup)system.deviceGroups[0]).deviceTypes[0]).deviceInstances[0]); Boolean checkLocked = deviceInstance.locked; //Seems like this method for accessing fields might have problems with multithreading foreach (DeviceGroup dg in system.deviceGroups) { foreach (DeviceType dt in dg.deviceTypes) { foreach (dynamic di in dt.deviceInstances) { checkLocked = di.locked; } } } } } public class System { public ArrayList deviceGroups = new ArrayList(); public System() { //API called to get names of all the DeviceGroups deviceGroups.Add(new DeviceGroup("Motherboard")); } } public class DeviceGroup { public ArrayList deviceTypes = new ArrayList(); public DeviceGroup() {} public DeviceGroup(string deviceGroupName) { //API called to get names of all the Devicetypes deviceTypes.Add(new DeviceType("Keyboard")); deviceTypes.Add(new DeviceType("Mouse")); } } public class DeviceType { public ArrayList deviceInstances = new ArrayList(); public bool deviceConnected; public DeviceType() {} public DeviceType(string DeviceType) { //API called to get hardwareIDs of all the device instances deviceInstances.Add(new Mouse("0001")); deviceInstances.Add(new Keyboard("0003")); deviceInstances.Add(new Keyboard("0004")); //Start thread CheckConnection that updates deviceConnected periodically } public void CheckConnection() { //API call to check connection and returns true this.deviceConnected = true; } } public class Keyboard { public string hardwareAddress; public bool keypress; public bool deviceConnected; public Keyboard() {} public Keyboard(string hardwareAddress) { this.hardwareAddress = hardwareAddress; //Start thread to update deviceConnected periodically } public void CheckKeyPress() { //if API returns true this.keypress = true; } } public class Mouse { public string hardwareAddress; public bool click; public Mouse() {} public Mouse(string hardwareAddress) { this.hardwareAddress = hardwareAddress; } public void CheckClick() { //if API returns true this.click = true; } } }

  • CakePHP - Paginate / Query: find lowest of multiple fields & order by it

    - by Atea
    I am using CakePHP for a price-comparison website. I have a table products with fields: id, pride_regular, price_action. I would like to combine the fields price_regular and price_action into a dynamic field: price. The lowest value of these two fields should be the value of the new price field. Also I want to order on it Ascending. Should I use a custom MySQL-query?

  • Is it okay to mix session data with form and querystring values in a custom model binder?

    - by Byron Sommardahl
    Working on a custom model binder in ASP.NET MVC 2. Most of the time I am binding data from typical form or querystring data. There are times that I end up letting the model binder bind part of an object and get the rest out of session at the controller action level. Does it make better sense to bind the entire object from the model binder (e.g. querystring, form, and session)?

  • run a function when a user clicks on any list element

    - by sova
    This is probably a very common question, but I was unable to find an answer myself; All my list elements call the function setQuery like this onClick="admin_stats.setQuery(this);" rather than [hardcode] add this to every list element, is there a way to simply have it run when a list element is clicked? I'm not very familiar with jQuery Live or binding/unbinding, but I think they would play a role here? Before I reinvent a rather square-looking wheel I thought I might ask =)

  • gnu screen - changing the default escape command key to ALT-X?

    - by Siva
    In GNU screen, I want to change the default command binding to Alt-s (by tweaking .screenrc) instead of the default C-a, the reason is I use emacs hence GNU screen binds the C-a key, sending "C-a" to the emacs becomes tedious (as @Nils said, to send "C-a" I should type "C-a a"), as well as "C-a" in bash shell, and I could change the escape to C- but some of them are already mapped in emacs and other combinations are not as easy as ALT-s . If anyone has already done a ALT key mapping, please do let me know.

  • Populating a Combobox inside a Gridview

    - by Nawait
    i'm having a few problems working with a gridview and a combobox inside of it. Here is the code for my ListView control: <ListView Height="139" HorizontalAlignment="Left" Margin="10,158,0,0" Name="lvAppointment" VerticalAlignment="Top" Width="250" MinWidth="350"> <ListView.View> <GridView> <GridViewColumn Header="Appointment" Width="120"> <GridViewColumn.CellTemplate> <DataTemplate> <DatePicker SelectedDate="{Binding Path=Appointment}"/> </DataTemplate> </GridViewColumn.CellTemplate> </GridViewColumn> <GridViewColumn Header="Type" Width="170"> <GridViewColumn.CellTemplate> <DataTemplate> <ComboBox ???/> </DataTemplate> </GridViewColumn.CellTemplate> </GridViewColumn> <GridViewColumn Header="Done" Width="50"> <GridViewColumn.CellTemplate> <DataTemplate> <CheckBox IsChecked="{Binding Path=Done}" IsThreeState="False"/> </DataTemplate> </GridViewColumn.CellTemplate> </GridViewColumn> </GridView> </ListView.View> I'm popluating the list from a sql ce database via c# with the following code using (SqlCeCommand sqlCeAppointment = new SqlCeCommand("SELECT appid,appointment,done,apptype.type FROM appointment INNER JOIN apptype ON appointment.refatid = apptype.atid WHERE refeventid = @eventid;", sqlCeConn)) { sqlCeAppointment.Parameters.AddWithValue("@eventid", ((cListEventItem)lvEvent.SelectedItems[0]).id); using (SqlCeDataReader sqlCeAppointmentReader = sqlCeAppointment.ExecuteReader()) { lvAppointment.Items.Clear(); while (sqlCeAppointmentReader.Read()) { lvAppointment.Items.Add(new cListAppointmentItem { id = sqlCeAppointmentReader.GetGuid(sqlCeTerminReader.GetOrdinal("appid")), Appointment = sqlCeAppointmentReader.GetDateTime(sqlCeTerminReader.GetOrdinal("appointment")), Type = sqlCeAppointmentReader.GetString(sqlCeTerminReader.GetOrdinal("type")), Done = sqlCeAppointmentReader.GetByte(sqlCeTerminReader.GetOrdinal("done")) }); } } } I can popluate the list just fine. But i want "Type" to be a combobox so the user can select the apropriate type of the appointment (its a list of appointments connected to an event). This combobox should be filled with data thats inside a table of the sql ce database (apptype). This table is not static, the users can add and delete items from this list. I have tried a few ways i found via google, but failed. I guess i'm having problems understanding how this works/should work. I hope someone can help me :( Thanks in advance

  • iPhone - Change entity class (NSManagedObject) to make them initializable

    - by ncohen
    Hi everyone, I would like to use my custom NSManagedObject like a normal object (as well as its regular functions). Is it possible to modify the class in order to be able to initialize it like a normal object? [[myManagedObject alloc] init]; Thanks edit: to clarify the question, will it screw everything up if I change the @dynamic with @synthesize in the implementation?
