ogre

I'm learning about using Ogre particles and had some questions about how the point type particles work.

Q. I believe point type particles are implemented as a single position. Is one single vertex is passed to the vertex shader?

Q. If one vertex is passed to the vertex shader then what gets sent to the fragment shader?

Q. Can I pass the particle size to the shader? Perhaps with a custom parameter?

How do multipass shaders work in OpenGL?

In Direct3D, multipass shaders are simple to use because you can literally define passes within a program. In OpenGL, it seems a bit more complex because it is possible to give a shader program as many vertex, geometry, and fragment shaders as you want. A popular example of a multipass shader is… >>> More
