Unigine::Shader Class
Header: | #include <UnigineShader.h> |
Interface for shader manipulation. Shader is an interface for loading shaders, setting parameter values, binding graphic context.
To get loaded shader programs, use special methods for corresponding Direct3D11 shaders or use getGLProgramID() to get the OpenGL shaders.
Shader class provides a lot of methods to set parameters (or arrays of parameters) to shader programs.
Usage Example#
This example demonstrates how to use your custom shaders (UUSL, GLSL, HLSL) to render a post-effect.
Add the following code to the AppWorldLogic.cpp file.
//...
ShaderPtr shader;
int AppWorldLogic::init()
{
// String containing the source code of the vertex shader (GLSL, HLSL, UUSL)
const auto vertex_shader = R"foo(
float4 main(float2 pos : POSITION) : SV_POSITION
{
return float4(pos, 0.0f, 1.0f);
}
)foo";
// String containing the source code of the fragment shader (GLSL, HLSL, UUSL)
const auto fragment_shader = R"foo(
cbuffer vars : register(b0)
{
float4 color;
};
float4 main(float4 fragCoord : SV_POSITION) : SV_TARGET
{
return color;
}
)foo";
shader = Shader::create();
// Loading vertex and fragment shaders and compiling them
shader->loadVertex(vertex_shader, "");
shader->loadFragment(fragment_shader, "");
shader->compile();
// Adding a render END_SCREEN callback to render the result as a post-effect
Render::addCallback(Render::CALLBACK_END_SCREEN,
MakeCallback([&]()
{
// Getting a post RenderTarget to render to
const auto rt = Renderer::getPostRenderTarget();
rt->unbindAll();
rt->bindColorTexture(0, Renderer::getTextureColor());
rt->enable();
// Binding our shader and rendering the screen via FFP
shader->bind();
// setting the fill color to magenta
shader->setParameterFloat4("color", Math::vec4(1.0f, 0.0f, 1.0f, 1.0f));
shader->flushParameters();
Ffp::renderScreen();
// Unbinding the shader and disabling the target
shader->unbind();
rt->disable();
}));
return 1;
}
// ...
