Detailed Description

Base class of vertex + fragment shaders (for Vulkan and OpenGL).

Constructor & Destructor Documentation

Shader()

Karma::Shader::Shader ( std::shared_ptr< UniformBufferObject > ubo )

inline

A constructor.

Parameters

ubo	Uniform buffer object to a assigned

Since

Karma 1.0.0

~Shader()

virtual Karma::Shader::~Shader ( )

virtualdefault

Destructor.

Since

Karma 1.0.0

Member Function Documentation

Bind() [1/2]

virtual void Karma::Shader::Bind ( ) const

inlinevirtual

Installs a shader (vertex + fragment) and uniform program object as part of current rendering state.

Todo

For OpenGL only. Vulkan Bind() is empty and may need abstract thinking

Since

Karma 1.0.0

Reimplemented in Karma::OpenGLShader, and Karma::VulkanShader.

Bind() [2/2]

virtual void Karma::Shader::Bind ( const std::string & texShaderNames ) const

inlinevirtual

Binding using name of texture.

Todo

Think with the previous binding routiine

Since

Karma 1.0.0

Reimplemented in Karma::OpenGLShader.

Create() [1/2]

Shader * Karma::Shader::Create ( const std::string & vertexSrc, const std::string & fragmentSrc )

static

Instantiating shader object according to the programmer chosen API.

Deprecated

Use the overloaded function with uniformbuffer object argument

Since

Karma 1.0.0

Create() [2/2]

Shader * Karma::Shader::Create ( const std::string & vertexSrcFile, const std::string & fragmentSrcFile, std::shared_ptr< UniformBufferObject > ubo, const std::string & shaderName = "NoNamedShader" )

static

For instantiating shader object accodring to programer's chosen API.

Parameters

vertexSrcFile	Path to vertex shader (filename included). For instance "../Resources/Shaders/shader.vert", relative to Engine's running directory
fragmentSrcFile	Path to fragment shader (filename included).
ubo	UniformBufferObject to be used
shaderName	Name of the shader to be supplied

Since

Karma 1.0.0

GetShaderName()

const std::string & Karma::Shader::GetShaderName ( ) const

inline

Getter for shader name.

Note

Could be a pointer?

Since

Karma 1.0.0

GetUniformBufferObject()

std::shared_ptr< UniformBufferObject > Karma::Shader::GetUniformBufferObject ( ) const

inline

Getter for uniform buffer object.

Returns

pointer to UniformBufferObject present in the shader

Since

Karma 1.0.0

UnBind()

virtual void Karma::Shader::UnBind ( ) const

inlinevirtual

Undo the binding of shader program.

Todo

Only OpenGL uses this, that too, for shader and not uniform. May need pondering over.

Since

Karma 1.0.0

Reimplemented in Karma::OpenGLShader, and Karma::VulkanShader.
