Shader class
#include <include/engine/graphics/shader.h>
Represents a compiled and linked GLSL shader program.
This class handles the lifecycle of a shader, from creation to binding and uniform setting.
Public static functions
- static auto CreateFromSource(const std::string& vertex_source, const std::string& fragment_source) -> std::shared_ptr<Shader>
- Loads vertex and fragment shader source code, compiles them, and links them into a single shader program.
- static auto Load(const std::string& path) -> std::shared_ptr<Shader>
- Placeholder Load method to satisfy the AssetManager requirement.
Constructors, destructors, conversion operators
- ~Shader()
- Deletes the shader program from the GPU.
Public functions
- auto id() const -> unsigned int
- Gets the OpenGL ID of the shader program.
- void Bind() const
- Activates this shader program for subsequent rendering calls.
- void Unbind() const
- Deactivates the currently bound shader program.
- void SetInt(const std::string& name, int value)
- Sets an integer uniform variable in the shader.
- void SetVec3(const std::string& name, glm::vec3 value)
- Sets a 3-component float vector uniform variable in the shader.
- void SetVec4(const std::string& name, glm::vec4 value)
- Sets a 4-component float vector uniform variable in the shader.
- void SetMat4(const std::string& name, glm::mat4 value)
- Sets a 4x4 matrix uniform variable in the shader.
Function documentation
static std::shared_ptr<Shader> engine::
Loads vertex and fragment shader source code, compiles them, and links them into a single shader program.
| Parameters | |
|---|---|
| vertex_source | A string containing the vertex shader source code. |
| fragment_source | A string containing the fragment shader source code. |
| Returns | A shared pointer to the newly created Shader object, or nullptr. |
static std::shared_ptr<Shader> engine::
Placeholder Load method to satisfy the AssetManager requirement.
| Parameters | |
|---|---|
| path | The path to the shader (not currently used for loading from disk). |
| Returns | A shared pointer to the Shader, or nullptr. |
Shaders are typically created from source in this engine.
unsigned int engine::
Gets the OpenGL ID of the shader program.
| Returns | The shader ID. |
|---|
void engine::
Sets an integer uniform variable in the shader.
| Parameters | |
|---|---|
| name | The name of the uniform variable in the GLSL code. |
| value | The integer value to set. |
void engine::
Sets a 3-component float vector uniform variable in the shader.
| Parameters | |
|---|---|
| name | The name of the uniform variable in the GLSL code. |
| value | The glm::vec3 value to set. |
void engine::
Sets a 4-component float vector uniform variable in the shader.
| Parameters | |
|---|---|
| name | The name of the uniform variable in the GLSL code. |
| value | The glm::vec4 value to set. |
void engine::
Sets a 4x4 matrix uniform variable in the shader.
| Parameters | |
|---|---|
| name | The name of the uniform variable in the GLSL code. |
| value | The glm::mat4 value to set. |
