Hello! I'm trying to implement bloom to my OpenGL game but I'm a bit confused. I want to create a second color attachment for saving the scene highlights. I'm using multisampled textures and have no idea how to do this.
Do I need to create two multi sampled color attachments? Two multisampledTextures like below?
glGenTextures(1, &multisampledTexture);
glBindTexture(GL_TEXTURE_2D_MULTISAMPLE, multisampledTexture);
glTexImage2DMultisample(GL_TEXTURE_2D_MULTISAMPLE, 4, GL_RGB, width, height, GL_TRUE);
glBindTexture(GL_TEXTURE_2D_MULTISAMPLE, 0);
glFramebufferTexture2D(GL_FRAMEBUFFER, GL_COLOR_ATTACHMENT0, GL_TEXTURE_2D_MULTISAMPLE, multisampledTexture, 0);I'm completely lost and don't know how to do this :( I don't want to know how to accomplish …
