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 … Web15 de mar. de 2016 · If we are going to move a texture map around by changing its texture coordinates , it is preferred that we use a “tileable” image that can be repeated over a surface. We set the texture map mode to gl.REPEAT so that texture coordinates that are transformed outside the range 0.0 to 1.0 map to a valid location in the texture image.
