Member Function Documentation

virtual int diguyDx11GraphicsShaderProgram::load_vertex_shader_source ( const char * filename_base )

virtual

This function will be called by DI-Guy when it is time for the vertex part of this shader to be loaded and compiled.

The utility function derive_diguy_shader_source_filename() can be used to convert the passed filename_base to an actual filename.

For example, assume that m_vertex_shader_filename is a character array of 512 bytes. The following function call would derive an appropriate vertex shader filename:

derive_diguy_shader_source_filename(m_vertex_shader_filename,
   511,
   filename_base,
   "glsl",
   "vert",
   1);

This function is called during the Build Stage.

Returns:

0 to indicate load was successful, -1 otherwise

Immediate Mode:

Immediate mode renderers usually do override this function.

Scene Graph:

Scene graph renderers usually do override this function.

Callable From:

N/A (automatically called by DI-Guy Graphics API during the Build Stage)

Reimplemented from diguyGraphicsShaderProgram.

virtual int diguyDx11GraphicsShaderProgram::load_pixel_shader_source ( const char * filename_base )

virtual

This function is the pixel shader (AKA fragment shader in OpenGL) equivalent of load_vertex_shader_source().

Reimplemented from diguyGraphicsShaderProgram.

virtual int diguyDx11GraphicsShaderProgram::reload ( )

virtual

Forces the underlying shader to reload. Returns 0 on success.

Reimplemented from diguyGraphicsShaderProgram.

virtual int diguyDx11GraphicsShaderProgram::link ( )

virtual

This function will be called by DI-Guy when it is time for the shader program to be linked.

This function is called during the Build Stage after the load_vertex_shader_source() and load_pixel_shader_source() functions.

Once the link has successfully completed shader variable bind indices can be looked up.

Returns:

0 to indicate link was successful, -1 otherwise

Immediate Mode:

Immediate mode renderers usually do override this function.

Scene Graph:

Scene graph renderers can override this function.

Callable From:

N/A (automatically called by DI-Guy Graphics API during the Build Stage)

Reimplemented from diguyGraphicsShaderProgram.

virtual int diguyDx11GraphicsShaderProgram::bind ( )

virtual

This function will be called by DI-Guy when this program is being bound for rendering.

It is during this function call that program level shader variables should be set. Program level variables will affect all shader operations in which this program is active. Variables that should affect specific instances of a shader should be set in diguyGraphicsShaderInstance::bind().

One example in the DI-Guy reference shaders is the ufrm_textures_enabled variable. Setting it to 0 will prevent textures from being applied during the shader program run.

This happens during the Draw Stage.

Immediate Mode:

Immediate mode renderers can override this function.

Scene Graph:

Scene graph renderers usually do not override this function; the renderer will typically do this internally. If shader variables need to be bound, however, this function should be overridden.

Callable From:

N/A (automatically called by DI-Guy Graphics API during the Draw Stage)

Reimplemented from diguyGraphicsShaderProgram.

virtual int diguyDx11GraphicsShaderProgram::unbind ( )

virtual

In general variables that were set in bind() should be unset or unbound here.

This happens during the Draw Stage.

Immediate Mode:

Immediate mode renderers can override this function.

Scene Graph:

Scene graph renderers usually do not override this function; the renderer will typically do this internally. If the bind() function was overridden, however, this function probably should be, too.

Callable From:

N/A (automatically called by DI-Guy Graphics API during the Draw Stage)

Reimplemented from diguyGraphicsShaderProgram.

virtual int diguyDx11GraphicsShaderProgram::bind_model_view_matrices	(	const float *	view_matrix,
		const float *	model_matrix
	)

virtual

virtual int diguyDx11GraphicsShaderProgram::bind_link_matrices	(	int	num_matrices,
		const float *	mat_data
	)

virtual

This function will be called by DI-Guy when the matrix data of a character's links needs to be sent to the graphics card.

For GLSL-based shaders, these values are typically passed into the vertex shader via uniform variables.

Note that the format of the data in mat_data will be affected by the bdiGraphicsInitGraphicsAPI variable transpose_shader_matrices value.

Immediate Mode:

Immediate mode renderers usually do override this function.

Scene Graph:

Scene graph renderers usually do not override this function, but instead use diguyGraphicsShape::get_shader_matrix_data() during the Update Stage.

Callable From:

N/A (automatically called by DI-Guy Graphics API during the Draw Stage)

Reimplemented from diguyGraphicsShaderProgram.

virtual int diguyDx11GraphicsShaderProgram::bind_color_array	(	int	num_colors,
		const float *	color_data
	)

virtual

This function will be called by DI-Guy when the color data of a character's links needs to be sent to the graphics card.

For GLSL-based shaders, these values are typically passed into the vertex shader via uniform variables.

Callable From:

N/A (automatically called by DI-Guy Graphics API during the Draw Stage)

Reimplemented from diguyGraphicsShaderProgram.

virtual void diguyDx11GraphicsShaderProgram::set_apply_matrices_flag ( int apply_matrices_flag )
