GL
Complete C++17 wrapper for OpenGL 4.6 Core Profile.
Dependencies
- OpenGL
- GLEW
- CUDA (optional, for interoperation support)
Building
- Follow the cmake build process for locating the dependencies.
- Toggle CUDA_INTEROP_SUPPORT for CUDA interoperation support. Note that the build will ask for the location of Cuda upon enabling this option.
Getting Started
Creating and uploading data to buffers:
#include <gl/all.hpp>
void buffer_example()
{
gl::buffer buffer;
std::vector<float> vertices(32);
buffer.set_data(sizeof(float) * vertices.size(), vertices.data());
}Creating and uploading data to textures:
#include <gl/all.hpp>
void texture_example()
{
gl::texture_1d texture_1d;
texture_1d.set_min_filter(GL_LINEAR);
texture_1d.set_mag_filter(GL_LINEAR);
texture_1d.set_wrap_s (GL_CLAMP );
std::array<float, 32> scalars;
texture_1d.set_storage (0, GL_RGBA, sizeof(float) * scalars.size());
texture_1d.set_sub_image (0, 0, scalars.size(), GL_RGBA, GL_FLOAT, scalars.data());
}Creating shaders and attaching them to programs:
#include <gl/all.hpp>
void shader_program_example()
{
gl::shader vert_shader(GL_VERTEX_SHADER);
vert_shader.load_source("vert_example.glsl");
gl::shader frag_shader(GL_FRAGMENT_SHADER);
frag_shader.load_source("frag_example.glsl");
gl::program program;
program.attach_shader(vert_shader);
program.attach_shader(frag_shader);
program.link();
program.use();
program.set_uniform(program.uniform_location("example_uniform"), 42);
program.unuse();
}Extensions
For adding GLM support to type-inferring uniform variable setters of the shader program, simply #include <gl/auxiliary/glm_uniforms.hpp>.
