+# WebGL2
 
+The **WebGL2** module supports graphics drawing, such as processing the graphics position and color. WebGL2 provides enhanced capabilities in the rendering pipeline and shader language than WebGL.
 
 This module provides WebGL APIs that correspond to the OpenGL ES 3.0 feature set. For more information, see [WebGL™](https://www.khronos.org/registry/webgl/specs/latest/2.0/).
