Automatic Mesh and Shader Level of Detail

Area of Science:

• Computer Graphics
• Real-time Rendering
• Geometric Modeling

Background:

• Level of Detail (LOD) is crucial for rendering optimization in graphics.
• Existing LOD techniques often focus on either geometric or shader simplification independently.
• A gap exists in simultaneously optimizing both mesh and shader details.

Purpose of the Study:

• To explore the combined benefits of geometric and shader simplification for rendering optimization.
• To introduce a novel discrete multiresolution representation integrating mesh and shader LODs.
• To develop automatic algorithms for generating these combined LODs.

Main Methods:

• Developed a new discrete multiresolution object representation.
• Integrated mesh and shader LODs at each resolution level.
• Proposed two automatic algorithms for adaptive simplification of meshes and shaders at varying distances.

Main Results:

• The proposed combined mesh and shader LOD achieves superior performance-quality tradeoffs.
• Demonstrated significant improvements over methods using only geometric or shader LODs.
• Validated the effectiveness of adaptive simplification algorithms.

Conclusions:

• Simultaneously simplifying geometry and shaders offers greater performance-quality flexibility.
• The presented discrete multiresolution representation and algorithms provide an effective solution for combined LOD generation.
• This approach advances rendering optimization techniques in computer graphics.
