Detailed Description

Definition at line 47 of file shader.h.


Constructor & Destructor Documentation

Shader::Shader ( CPT(ShaderFile name,
CPT(ShaderFile text,
const ShaderLanguage &  lang = SL_none 
)

Construct a Shader.

Definition at line 1857 of file shader.cxx.


Member Function Documentation

const bool Shader::get_error_flag ( ) const [inline]

Returns true if the shader contains a compile-time error.

This doesn't tell you whether or not the shader is supported on the current video card.

Definition at line 78 of file shader.I.

const Filename Shader::get_filename ( const ShaderType &  type = ST_none) const [inline]

Return the Shader's filename for the given shader type.

Definition at line 22 of file shader.I.

const Shader::ShaderLanguage Shader::get_language ( ) const [inline]

Returns the shader language in which this shader was written.

Definition at line 132 of file shader.I.

ShaderUtilization Shader::get_shader_utilization ( ) [inline, static]

This flag returns SUT_none, SUT_basic, or SUT_advanced and controls the automatic generation of shaders.

It is initialized from the config variable of the same name, but it can be subsequently adjusted.

Definition at line 104 of file shader.I.

const string & Shader::get_text ( const ShaderType &  type = ST_none) const [inline]

Return the Shader's text for the given shader type.

Definition at line 49 of file shader.I.

bool Shader::have_shader_utilization ( ) [inline, static]

If true, then get_shader_utilization has been set using set_shader_utilization.

If false, then get_shader_utilization simply returns the config variable of the same name.

Definition at line 121 of file shader.I.

static void Shader::init_type ( ) [inline, static]

This function is declared non-inline to work around a compiler bug in g++ 2.96.

Making it inline seems to cause problems in the optimizer.

Reimplemented from TypedReferenceCount.

Definition at line 505 of file shader.h.

References TypedReferenceCount::init_type().

void Shader::set_shader_utilization ( ShaderUtilization  utl) [inline, static]

Set this flag to SUT_none, SUT_basic, or SUT_advanced to limit panda's automatic shader generation facilities.

Definition at line 90 of file shader.I.
