[Opensg-users] Float 1D Array to shader

[Victor H. <vic...@gm...>]

Hi all!

I have a problem with passing a 1D Array of floats to my shader:

TextureObjChunk::initialize image failed: invalid value(0x501)

This error happens when I try to use a 1D Image:
img->set( Image::OSG_RGBA_PF, N, 1, 1, 1, 1, 0, (UChar8*) &buffer[0],
OSG::Image::OSG_FLOAT32_IMAGEDATA);

where buffer is a std vector<float> with size 4*N

Texture:
tex_obj_chunk->setTarget(GL_TEXTURE_1D);
tex_obj_chunk->setInternalFormat(GL_RGBA_FLOAT32_ATI);

I am not sure what enum I have to use, I think there is an obvious
mistake.. (I hope so ;))


Best regards,
Victor
