Opengl 4.6 |work| ❲OFFICIAL 2024❳

OpenGL 4.6 also introduces several extensions that provide additional functionality, including:

| Aspect | OpenGL 4.6 | Vulkan 1.3+ | |--------|------------|--------------| | Abstraction | High (state machine) | Low (explicit) | | Shader path | GLSL or SPIR-V | SPIR-V only | | Multi-threading | Limited (shared context) | Excellent (explicit queues) | | GPU-driven content | Via buffer_device_address | Native | | Error checking | Driver does most | Application + validation | | Learning curve | Moderate | Steep | opengl 4.6

| Feature | Description | |---------|-------------| | buffer_reference | 64-bit GPU pointer types | | buffer_reference_align | Alignment control for referenced blocks | | spirv_intrinsics | Direct SPIR-V instruction emission (advanced) | | gl_BaseInstanceARB | Available in all shader stages (was vertex-only) | | Extended constant folding | Compile-time evaluation improvements | OpenGL 4

// Bind the VAO and VBO glBindVertexArray(vao); glBindBuffer(GL_ARRAY_BUFFER, vbo); opengl 4.6

The OpenGL 4.6 pipeline consists of the following stages:
