Function rs2_gl_init_rendering

Function Documentation

void rs2_gl_init_rendering(int api_version, int use_glsl, rs2_error **error)

Initialize rendering pipeline. This function must be called before executing any of the rendering blocks. Rendering blocks do not handle threading, and assume all calls (including init / shutdown) Until initialized, rendering blocks will do nothing (function as bypass filters) are serialized and coming from a single rendering thread

Parameters:

  • api_version – [in] Users are expected to pass their version of RS2_API_VERSION to make sure they are running the correct librealsense version.

  • use_glsl – [in] On modern GPUs you can get slightly better performance using GLSL However, this assumes the current rendering context is v3+ Setting use_glsl to false will use legacy OpenGL calls This in turn assumes the rendering context is either version < 3, or is a compatibility context

  • error – [out] if non-null, receives any error that occurs during this call, otherwise, errors are ignored
