geometry shaders

Geometry shaders are a stage in computer graphics processing that take existing 3D objects and modify or generate new shapes on the fly. They operate between the vertex shader, which processes individual points, and the fragment shader, which colors pixels. Geometry shaders can create new geometric primitives—like additional triangles or lines—from existing ones, allowing for dynamic effects such as adding details, shadows, or simulating complex phenomena. This capability enhances visual realism and efficiency by reducing the need for pre-designed models, making graphics more versatile and responsive to real-time rendering demands.
