Constructor & Destructor Documentation

◆ At()

Ogre::RTShader::At::At ( ParameterPtr  p)
inline

Member Function Documentation

◆ getParameter()

const ParameterPtr& Ogre::RTShader::Operand::getParameter ( ) const
inlineinherited

Returns the parameter object as weak reference.

◆ hasFreeFields()

bool Ogre::RTShader::Operand::hasFreeFields ( ) const
inlineinherited

Returns true if not all fields used.

(usage is described through semantic)

◆ getMask()

int Ogre::RTShader::Operand::getMask ( ) const
inlineinherited

Returns the mask bitfield.

◆ x()

Operand& Ogre::RTShader::Operand::x ( )
inlineinherited

◆ y()

Operand& Ogre::RTShader::Operand::y ( )
inlineinherited

◆ z()

Operand& Ogre::RTShader::Operand::z ( )
inlineinherited

◆ w()

Operand& Ogre::RTShader::Operand::w ( )
inlineinherited

◆ xy()

Operand& Ogre::RTShader::Operand::xy ( )
inlineinherited

◆ xyz()

Operand& Ogre::RTShader::Operand::xyz ( )
inlineinherited

◆ mask()

Operand& Ogre::RTShader::Operand::mask ( int  opMask)
inlineinherited

◆ setMaskToParamType()

void Ogre::RTShader::Operand::setMaskToParamType ( )
inherited

automatically set swizzle to match parameter arity

◆ getSemantic()

OpSemantic Ogre::RTShader::Operand::getSemantic ( ) const
inlineinherited

Returns the operand semantic (do we read/write or both with the parameter).

◆ getIndirectionLevel()

ushort Ogre::RTShader::Operand::getIndirectionLevel ( ) const
inlineinherited

Returns the level of indirection.

The greater the indirection level the more the parameter needs to be nested in brackets. For example given 4 parameters x1...x4 with the indirections levels 0,1,1,2 respectively. The parameters should form the following string: x1[x2][x3[x4]].

◆ toString()

String Ogre::RTShader::Operand::toString ( ) const
inherited

Returns the parameter name and the usage mask like this 'color.xyz'.

◆ getMaskAsString()

static String Ogre::RTShader::Operand::getMaskAsString ( int  mask)
staticinherited

Returns the given mask as string representation.

◆ getFloatCount()

static int Ogre::RTShader::Operand::getFloatCount ( int  mask)
staticinherited

Return the float count of the given mask.

◆ getGpuConstantType()

static GpuConstantType Ogre::RTShader::Operand::getGpuConstantType ( int  mask)
staticinherited

Return the gpu constant type of the given mask.
