GLSL Shader.
A vtkShader2 object is made of a source code encoded into a string and a type, identifying the hardware programmable stage it is attached to. Hardware programmable stages are (or will be)

Default constructor.
SourceCode is NULL. Type is vertex.
|
protectedvirtual |
Destructor.
Delete SourceCode and LastCompileLog if any.

|
virtual |
Return 1 if this class is the same type of (or a subclass of) the named class.
Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.
Reimplemented from vtkObjectBase.

vtkShader2* vtkShader2::NewInstance | ( | ) | const |
|
virtual |
|
static |
Returns if the context supports the required extensions.
Extensions are load when the context is set.
|
virtual |
String containing the shader source code.
Reminder SetString makes a copy of its argument.
|
virtual |
|
virtual |
Return the shader type, .
|
virtual |
Set the shader type, .
const char* vtkShader2::GetTypeAsString | ( | ) |
Return the shader type as a string.
void vtkShader2::Compile | ( | ) |
Compile the shader code.
The result of compilation can be query with GetLastCompileStatus() The log of compilation can be query with GetLastCompileLog()
bool vtkShader2::GetLastCompileStatus | ( | ) |
Tells if the last call to compile succeeded (true) or not (false).
Initial value is false.
const char* vtkShader2::GetLastCompileLog | ( | ) |
Return the log of the last call to compile as a string.
Initial value is the empty string ""='\0'.
void vtkShader2::SetContext | ( | vtkRenderWindow * | context | ) |
Get/Set the context.
This does not increase the reference count of the context to avoid reference loops. SetContext() may raise an error is the OpenGL context does not support the required OpenGL extensions.
vtkRenderWindow* vtkShader2::GetContext | ( | ) |
|
virtual |
Release OpenGL resource (shader id).
|
virtual |
Return the OpenGL shader object id.
|
virtual |
Get/Set the list of uniform variables values.
Initial value is an empty list (not null pointer).
|
virtual |
|
protected |
Load the required OpenGL extensions.
