WebContexts are localized within a particular process of execution (an application, more or less) on an operating system. A process can create multiple OpenGL contexts. Each context can represent a separate viewable surface, like a window in an application. Each context has its own set of OpenGL Objects, which are independent of those from other ... Web6 de nov. de 2011 · You have two options for accessing this depth texture: a) reading the 0…1 depth values directly out of the texture, or b) having the hardware do a depth comparison as part of the texture lookup and return to you a 0…1 “occlusion” result (if this is a shadow map). It sounds like you want a) (read the 0…1 depth values directly).

In order to unconditionally write to the depth buffer, the depth test should be enabled and set to GL_ALWAYS (see glDepthFunc). Web11 de dez. de 2024 · The glClear function takes a single argument ( mask) that is the bitwise OR of several values indicating which buffer is to be cleared. The value to which each buffer is cleared depends on the setting of the clear value for that buffer. If a buffer is not present, a glClear call directed at that buffer has no effect.
