Detailed Description
Shader class. This class loads, compiles and represents shaders.
Constructor & Destructor Documentation
| sgShader::sgShader | ( | ) |
Constructor. Sets up an instance of this class without a shader.
| sgShader::sgShader | ( | const char * | vsfilename, | |
| const char * | fsfilename | |||
| ) |
Constructor. Sets up an instance of this class and assigns a shader programm compiled from the given files.
- Parameters:
-
vsfilename name of the textfile containing the vertex shader of the type .vsh, without the type specifier fsfilename name of the textfile containing the fragment shader of the type .fsh, without the type specifier
| sgShader::~sgShader | ( | ) |
Deconstructor. The deconstructor.
Member Function Documentation
| void sgShader::destroy | ( | ) | [virtual] |
Create shader. Creates a new shader for the current instance from the given files.
- Parameters:
-
vsfilename name of the textfile containing the vertex shader of the type .vsh, without the type specifier fsfilename name of the textfile containing the fragment shader of the type .fsh, without the type specifier
- Returns:
- pointer to the shaders instance
Reimplemented from sgBase.
| sgShader * sgShader::getShader | ( | unsigned int | shad | ) | [static] |
Get shader. Returns the pointer to an instance of a default shader identified by the given number.
- Parameters:
-
shad id of the default shader to return (0 for no shading, 1 for shading)
- Returns:
- pointer to the shaders instance
| sgShader * sgShader::getShader | ( | const char * | vsfilename, | |
| const char * | fsfilename | |||
| ) | [static] |
Get shader. Checks, if there is a shader of the given filenames or create a new one otherwize.
- Parameters:
-
vsfilename name of the textfile containing the vertex shader of the type .vsh, without the type specifier fsfilename name of the textfile containing the fragment shader of the type .fsh, without the type specifier
- Returns:
- pointer to the shaders instance
| BOOL sgShader::validateProgram | ( | ) |
Validate shader program. Checks if the shader is setup correctly.
- Returns:
- TRUE if everything is fine, FALSE otherwize
Member Data Documentation
