  • How to draw a spotlight in 3D

    - by RecursiveCall
    To be clear, I am not talking about the light result (the lit area) but the spotlight itself, like this The two common suggestions that I tried are 2D image and a 3D cone. The problem with the pre-regenerated 2D image is that it always look 2D and flat no matter how it is rotated in world space. The cone on the other hand is next to impossible to control when it comes to fade distance, it doesn't look soft (smooth) and it is expensive to compute.

  • C++ Without Source Files

    - by Snowman
    Bjarne Stroustrup mentions in his book "The C++ Programming Language, 4th Edition" that not all C++ implementations use files to store and compile code: There are systems that do not store, compile, and present C++ programs to the programmer as sets of files. (Chapter 15, page 419) Later in the chapter, he reiterates that certain implementations do not use files but he does not give any examples. How would such an environment function compared to a more common file-based environment?

  • Application workflow

    - by manseuk
    I am in the planning process for a new application, the application will be written in PHP (using the Symfony 2 framework) but I'm not sure how relevant that is. The application will be browser based, although there will eventually be API access for other systems to interact with the data stored within the application, again probably not relavent at this point. The application manages SIM cards for lots of different providers - each SIM card belongs to a single provider but a single customer might have many SIM cards across many providers. The application allows the user to perform actions against the SIM card - for example Activate it, Barr it, Check on its status etc Some of the providers provide an API for doing this - so a single access point with multiple methods eg activateSIM, getStatus, barrSIM etc. The method names differ for each provider and some providers offer methods for extra functions that others don't. Some providers don't have APIs but do offer these methods by sending emails with attachments - the attachments are normally a CSV file that contains the SIM reference and action required - the email is processed by the provider and replied to once the action has been complete. To give you an example - the front end of my application will provide a customer with a list of SIM cards they own and give them access to the actions that are provided by the provider of each specific SIM card - some methods may require extra data which will either be stored in the backend or collected from the user frontend. Once the user has selected their action and added any required data I will handle the process in the backend and provide either instant feedback, in the case of the providers with APIs, or start the process off by sending an email and waiting for its reply before processing it and updating the backend so that next time the user checks the SIM card its status is correct (ie updated by a backend process). My reason for creating this question is because I'm stuck !! I'm confused about how to approach the actual workflow logic. I was thinking about creating a Provider Interface with the most common methods getStatus, activateSIM and barrSIM and then implementing that interface for each provider. So class Provider1 implements Provider - Then use a Factory to create the required class depending on user selected SIM card and invoking the method selected. This would work fine if all providers offered the same methods but they don't - there are a subset which are common but some providers offer extra methods - how can I implement that flexibly ? How can I deal with the processes where the workflow is different - ie some methods require and API call and value returned and some require an email to be sent and the next stage of the process doesn't start until the email reply is recieved ... Please help ! (I hope this is a readable question and that this is the correct place to be asking) Update I guess what I'm trying to avoid is a big if or switch / case statement - some design pattern that gives me a flexible approach to implementing this kind of fluid workflow .. anyone ?

  • admin-over-clients application

    I have the same web application running on several different servers. Now I want a central place to administer everything in one web interface. What is the best way to do this?

    - by Sebastian
    This might seem like a common question that have been already solved. Well, I checked many tutorials, question and googled a lot but almost everything failed after all. The main problem is that I do not have gconf-editor and even if I install it, I don't have an "/apps/nautilus/preferences/show_desktop" option to uncheck to finish whole quite known compiz tweak. Does anybody managed this issue on Xubuntu 13.04? May I ask how? Thank you in advance.

  • Looking for wireless product

    - by Belinda
    Can anyone suggest some options for me? I would like to provide our maintenance department with a view-only monitor showing our common Outlook calendars. I'm guessing it would have to have some touch-screen capabilities since they would need to be able to toggle between several calendars. We do have a cobbled together, building wide wireless network. I don't want anything that needs to be "wired or cabled" just plugged into a power source and mounted on the wall.
