Detailed Description

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)

  1. vertex shader
  2. tessellation control shader
  3. tessellation evaluation shader
  4. geometry shader
  5. fragment shader

Note: tessellation control shader is called hull shader in DirectX11 Note: tessellation evaluation shader is called domain shader in DirectX11 Ref: OpenGL spec 4.0 http://www.opengl.org/registry/doc/glspec40.core.20100311.withchanges.pdf Ref: "Introducing DirectX 11" http://www.gamasutra.com/view/feature/3759/sponsored_feature_introducing_.php

Constructor & Destructor Documentation

vtkShader2::vtkShader2 ( )
protected

Default constructor. SourceCode is NULL. Type is vertex.

virtual vtkShader2::~vtkShader2 ( )
protectedvirtual

Destructor. Delete SourceCode and LastCompileLog if any.

Member Function Documentation

static vtkShader2* vtkShader2::New ( )
static
static int vtkShader2::IsTypeOf ( const char *  type)
static
virtual int vtkShader2::IsA ( const char *  name)
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 vtkObject.

static vtkShader2* vtkShader2::SafeDownCast ( vtkObjectBase o)
static
virtual vtkObjectBase* vtkShader2::NewInstanceInternal ( ) const
protectedvirtual

Reimplemented from vtkObject.

vtkShader2* vtkShader2::NewInstance ( ) const
void vtkShader2::PrintSelf ( ostream &  os,
vtkIndent  indent 
)
virtual

Methods invoked by print to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from vtkObject.

static bool vtkShader2::IsSupported ( vtkRenderWindow context)
static

Returns if the context supports the required extensions. Extensions are load when the context is set.

virtual char* vtkShader2::GetSourceCode ( )
virtual

String containing the shader source code. Reminder SetString makes a copy of its argument.

virtual void vtkShader2::SetSourceCode ( const char *  )
virtual

String containing the shader source code. Reminder SetString makes a copy of its argument.

virtual int vtkShader2::GetType ( )
virtual

Return the shader type, .

Postcondition
valid_result: result==VTK_SHADER_TYPE_VERTEX || result==VTK_SHADER_TYPE_TESSELLATION_CONTROL || result==VTK_SHADER_TYPE_TESSELLATION_EVALUATION || result==VTK_SHADER_TYPE_GEOMETRY || result==VTK_SHADER_TYPE_FRAGMENT.
virtual void vtkShader2::SetType ( int  )
virtual

Set the shader type, .

Precondition
valid_type: type==VTK_SHADER_TYPE_VERTEX || type==VTK_SHADER_TYPE_TESSELLATION_CONTROL || type==VTK_SHADER_TYPE_TESSELLATION_EVALUATION || type==VTK_SHADER_TYPE_GEOMETRY || type==VTK_SHADER_TYPE_FRAGMENT.
Postcondition
is_set: GetType()==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()

Precondition
SourceCode_exists: this->GetSourceCode()!=0
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'.

Postcondition
result_exists: result!=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 ( )

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.

virtual void vtkShader2::ReleaseGraphicsResources ( )
virtual

Release OpenGL resource (shader id).

virtual unsigned int vtkShader2::GetId ( )
virtual

Return the OpenGL shader object id.

virtual vtkUniformVariables* vtkShader2::GetUniformVariables ( )
virtual

Get/Set the list of uniform variables values. Initial value is an empty list (not null pointer).

virtual void vtkShader2::SetUniformVariables ( vtkUniformVariables variables)
virtual

Get/Set the list of uniform variables values. Initial value is an empty list (not null pointer).

bool vtkShader2::LoadRequiredExtensions ( vtkRenderWindow context)
protected

Load the required OpenGL extensions.
