Hi, Yesterday i played a bit with reactive-fieldtrip and it is a lot of fun. What are the future plans to deal with handles to gpu data, like texture, shader, and buffer objects ? Because i thought it might be a good idea to use vertex buffer objects for the geometry since with OpenGL 3.0 the glBegin/glEnd (and much more) is obsolete. So i built data types for a static vertex buffer object and a static index buffer object and made them an instance of Renderable. What the thing is, is that i can create the bufferobject only after the creation of the OpenGL context. That's why i use unsafePerformIO as i have seen in an obj file example.
vboGeom :: Geometry3 vboGeom = renderableG geom where geom = unsafePerformIO $ loadVbo cubeVertexData cubeTriIndices
Not very elegant. So are there any ideas on that ? Btw, i could post the functions and data types for my vertex buffer example if anyone likes to see them. kind regards, Andreas -- Andreas-C.
