Detailed Description

template<typename T, class LocationInit, class Typechecker, class SpecOpsWrapper>
class oglplus::UniformSpecOps< T, LocationInit, Typechecker, SpecOpsWrapper >

Base template for Uniform and ProgramUniform.

Note

Do not use this class directly use Uniform, ProgramUniform or one of the other derived uniform classes instead.

Member Function Documentation

Program::ActiveVariableInfo oglplus::UniformOps< LocationInit , Typechecker >::Info ( void  )

inherited

Returns a Program::ActiveVariableInfo for this uniform.

Note that this is a rather inefficient operation.

bool oglplus::UniformOps< LocationInit , Typechecker >::IsActive ( void  )

inherited

Tests if this Uniform is initialized and can be used.

For Uniform and ProgramUniform this function always returns true as these cannot be in uninitialized state. For LazyUniform, LazyProgramUniform, OptionalUniform, etc. this function returns true if the uniform is active and can be used for subsequent value-setting operations. If this function returns false then trying to set a value or any other operation on the uniform besides destruction throws an exception.

template<typename... P>

void oglplus::UniformSpecOps< T, LocationInit, Typechecker, SpecOpsWrapper >::SetVector	(	T	v,
		P...	p
	)

Set the vector value of the uniform variable.

This function can be used to set uniform variables with 2, 3 or 4 -component vector types with the same underlying type as is the template parameter of the Uniform or ProgramUniform class. For example Uniform<GLfloat>::SetVector() can be used to set the values of GLSL uniforms with vec2, vec3 or vec4 type, Uniform<GLint>::SetVector() can be used to set the values of GLSL uniforms with ivec2, ivec3 or ivec4 type, etc.

Note

Consider using Uniform<Vector<T,N>>Set() instead of Uniform<T>::SetVector<N>().

This function is not intended for setting arrays of uniform variables.

Set the vector value of the uniform variable.

This function can be used to set uniform variables with 2, 3 or 4 -component vector types with the same underlying type as is the template parameter of the Uniform or ProgramUniform class.

For example Uniform<GLfloat>::SetVector() can be used to set the values of GLSL uniforms with vec2, vec3 or vec4 type, Uniform<GLint>::SetVector() can be used to set the values of GLSL uniforms with ivec2, ivec3 or ivec4 type, etc.

template<std::size_t Cols>

void oglplus::UniformSpecOps< T, LocationInit, Typechecker, SpecOpsWrapper >::SetVectors	(	GLsizei	count,

	)

Set multiple scalar or vector values of an uniform variable.

This function can be used to set multiple values of an uniform array variable with scalar or vector type with 2, 3 or 4 -components with the same underlying type as is the template parameter of the Uniform or ProgramUniform class.

For example Uniform<GLfloat>::SetVector() can be used to set the values of GLSL uniforms with vec2, vec3 or vec4 type, Uniform<GLint>::SetVector() can be used to set the values of GLSL uniforms with ivec2, ivec3 or ivec4 type, etc.

Note

Consider using Uniform<T>::Set() or Uniform<Vector<T,N>>Set() instead of SetVectors.
