Hello
I’m implementing a front to back slice volume rendering and I am having issues with blending.
Basically I should be using glBlendFunc(GL_ONE_MINUS_DST_ALPHA,GL_ONE); but it does not work while on Linux using glBlendFunc(GL_ONE_MINUS_SRC_ALPHA,GL_ONE); works!!! I’m also testing on macbook and glBlendFunc(GL_ONE_MINUS_DST_ALPHA,GL_ONE); works there (as it should). Also with only glBlendFunc(GL_ONE_MINUS_SRC_ALPHA,GL_ONE); I am having issue when the background is white!!!
Would anybody know why this could be???
Versions of OpenGL
Macbook: Opengl 2.1
Linux: Opengl 4.1
Thanks
Pascal
