Lumina-0.2.8 is out
|
I've released a new version of Lumina, a platform independent GLSL IDE. The new version supports a profiler to determine the average shader run time.

The first screenshot are some gears with 8 lights and dual parabolic shadows. All 16 shadowmaps share the same 4096x4096 texture. There are 16 passes needed to generate the... |

GLSL hardware skinning

the 512 are the minimum that have to be supported. and that are vec4, That is enough for up to 64 matrices. Because some of them are required for other uniforms up to 60 bones are realistic...

What happens when multiplying by projection matrix
|
if a Vertex is multiplied with the gl_(ModelView)ProjectionMatrix it is in a 4 dimensional unnamed space. After the dividing the XY and Z component by W the vertex is in postperspective space (range [-1.0.... 1.0] for XYZ if the vertex is located ins... |

Particles System OpenSG or GLSL
|
Rotating of pointsprites can be done with a few fragment shader instructions. And the size limit isn't a big problem if larger sprites would be clipped away by the near plane.

questions about CG,GLSL.assembly shaders in OpenGL
|
1. GLSL can be available in OpenGL 1.5 as extension. (In that case the driver update won't be a wrong idea)
2. No, the required GPU is depend on the shader profile.
3. The old ARB shaders are very limited... |

Implements the vertex blending
|
Matrix palette skinning? That won't work without vertex shaders. There are old deprecated extension like GL_ARB_matrix_palette and GL_ARB_vertex_blend, but both are not supported anymore.

Points Selection
|
It is much faster if each point is rendered with another color into the back buffer (16m or 2³² should be enough) After that read the pixel below the mouse with glReadPixel. The opengl picking is not supported in hardware on many cards... |

Pbuffer
|
Pbuffers can be used to render into a texture, but it's recommend to use FBOs (frame buffer objects) instead. |

GLSL: Bump mapping. Is tangent needed?
|
Bumpmapping won't work without tangents (bitangents can be calculated with a cross product. The calculation is simple:
v[0...2] vertex position
t[0...2] texcoords
tan.xyz = (v1-v0).xyz * (t2-t0).y - (v2-v0).xyz * (t1-t0).y;
