Study Notes

3D Rendering

  • Rendering converts 2D/3D geometry into images/videos.
  • It takes 3D scene data (polygons, materials, textures, and lighting) and computes a final image.
  • User controls four main factors: Geometry, Cameras, Lights, Materials.

Geometry

  • Geometry is the fundamental element in a 3D scene.
  • Only 3D geometry can be rendered.

Cameras

  • Cameras are needed to view the geometry.
  • CG cameras mimic real-world cameras (focal length, field of view, depth of field).

Lights

  • Lights illuminate the scene.
  • Absence of light results in a dark scene.
  • Light interactions with geometry define highlights and shadows.

Materials

  • Materials (color, texture, etc.) combine in rendering to form the final image pixels.

Rendering in Computer Systems

  • Rendering is performed by the CPU or GPU, or a combination.

CPU-Based Rendering

  • CPUs use multiple cores to process data at high speeds.
  • More cores lead to better rendering performance.
  • Ideal for complex scenes with many details (e.g., architectural designs).

GPU-Based Rendering

  • GPUs have thousands of small cores for high-performance rendering.
  • Used for real-time processing (30-120 frames per second).
  • Can preview renderings without long wait times.
  • Useful for adding lights and textures to 3D models.

Rendering Process Steps

  • 3D Modeling: Creating a digital 3D model using software.
  • Materials and Texturing: Applying accurate materials to objects for realism
  • Lighting: Setting lighting conditions matching real-world lighting.
  • Rendering: Generating the image based on model, materials, and lighting.
  • Refining: Final adjustments to fine-tune the rendering (lighting, texturing, etc. and adds realism)
