Setting texture dimensions using c interface #473

Closed hieronymusanthonius closed 3 years ago

hieronymusanthonius commented 3 years ago

I got ospray running in a UWP app with a few issues. I am using the c interface and I cannot figure out how to set the texture dimensions ? Anybody a hint please?

Texture dimensions are inferred from the data array, thus for textures use a 2D array with the dimensions of the texture image:

OSPData data = ospNewSharedData(texturePtr, type, width, 0, height);

"Type" should be a compatible type to the texture format, e.g. OSP_VEC4UC for OSP_TEXTURE_SRGBA.
