Textures

You have to download the textures from the Release and place Textures directory in your root directory for build properly.

Techniques

• View frustum culling with QuadTree
  • 1 index buffer per QuadTree, execute 1 Draw Call on each QuadTrees
  • Each frame, Check view frustum contains OBB of QuadNode
  • Each frame, Update index buffer (default heap) with CopyBufferRegion
• Distance based tessellation factor calculation
• Matching QuadNode border tessellation factors
  • By estimating adjacent tessellation factors of QuadNode
  • For preventing crack
• Matching cube border teseellation factors
• Shadow mapping with PCF (Percentage-Closer Filtering)
