|
Copy constructor using CopyOp to manage deep vs shallow copy. |
|
|
|
|
|
For a given GL context, attach a glShader to a glProgram |
|
|
|
If needed, compile the PCS's glShader |
|
Mark internal glShader for deletion. Deletion requests are queued tuntil they can be executed in the proper GL context. |
|
Mark our PCSs as needing recompilation. Also mark Programs that depend on us as needing relink |
|
flush all the cached glShaders which need to be deleted in the OpenGL context related to contextID. |
|
Query InfoLog from a glShader |
|
|
|
Query the shader's source code text |
|
Get the Shader type as an enum. |
|
|
|
Get the Shader type as a descriptive string. |
|
Load the Shader's source code text from a file. |
|
|
|
Read shader source from file and then constructor shader of specified type. Return the resulting Shader or 0 if no valid shader source code be read. |
|
release OpenGL objects in specified graphics context if State object is passed, otherwise release OpenGL objects for all graphics context if State object pointer NULL. Reimplemented from osg::Object. |
|
|
|
Load the Shader's source code text from a string. |
