Question

glTexParameterf(GL_TEXTURE_RECTANGLE, GL_TEXTURE_WRAP_T, GL_REPEAT);
GLuint err = glGetError();

If I set GL_TEXTURE_RECTANGLE's GL_TEXTURE_WARP to GL_REPEAT, glGetError() will always return

GL_INVALID_OPERATION.

: GL_TEXTURE_RECTANGLE -> GL_TEXTURE_2D  return GL_NO_ERRORS

: GL_REPEAT -> GL_CLAMP return GL_NO_ERRORS

…How to solve this?

i need to call `glTexParameterf(GL_TEXTURE_RECTANGLE, GL_TEXTURE_WRAP_T, GL_REPEAT);

— sorry about this post… Stupid.. TEXTURE_RECTANGLE not allow GL_REPEAT…

I don’t know all the details, but the short answer is: GL_TEXTURE_RECTANGLE doesn’t support GL_REPEAT. You’ll have to find another solution.
