Web25 de ago. de 2016 · This article discusses how to improve OpenGL* performance by swapping Frame Buffer Objects (FBO) instead of using a single FBO and swapping surfaces. Swapping is useful when making multiple changes to a rendered image, such as switching color, depth, or stencil attachments. The recommendation is to use dedicated … WebTo attach a stencil buffer you use GL_STENCIL_ATTACHMENT as the second argument and specify the texture's formats as GL_STENCIL_INDEX . It is also possible to attach both a depth buffer and a stencil buffer as a single texture. Each 32 bit value of the texture then contains 24 bits of depth information and 8 bits of stencil information. did it\u0027s a wonderful life win an oscar

"43 In modern OpenGL there are 4 different methods to update 2D textures: glTexImage2D - the slowest one, recreates internal data structures. glTexSubImage2D - a bit faster, but can't change the parameters (size, pixel format) of the image. Render-to-texture with FBO - update texture entirely on GPU, very fast. " - Opengl change texture
