To create realistic and immersive virtual environments.

To generate 3D models for games and simulations.

To process and display real-time data.

To enhance the visual quality of images and videos.

Ray tracing

Rasterization

Voxel-based rendering

Volume rendering

Forward rendering processes pixels in a front-to-back order, while deferred rendering processes pixels in a back-to-front order.

Forward rendering stores all lighting information in the framebuffer, while deferred rendering stores only depth and normal information.

Forward rendering is more efficient for scenes with many light sources, while deferred rendering is more efficient for scenes with many objects.

Forward rendering is used in VR, while deferred rendering is used in AR.

To reduce the computational cost of rendering by focusing on the area of the scene that the user is currently looking at.

To improve the visual quality of the rendered image by increasing the resolution in the area of the scene that the user is currently looking at.

To create a more immersive virtual environment by simulating the natural movement of the human eye.

To reduce the latency of the rendered image by pre-rendering the areas of the scene that the user is likely to look at next.

The high computational cost of rendering realistic and immersive virtual environments.

The need for specialized hardware to support VR and AR applications.
