Demos that are made up of meshes. These include actors, terrains and freeforms.

Terrain Renderer

  • Archipalego
    • Advanced terrain renderer demo demonstrating the use of high resolution terrain textures
  • Multiple Height Data Sources With One Terrain
    • Demonstrates a height data source that uses multiple grey scale bitmaps of different scales to create a terrain
  • Perlin Noise Generated Terrain
    • Demontrates TGLPerlinHDS to create a mountain range on a terrain
  • Shaded Terrain
    • Terrain with shadows
  • Shaded Terrain with Aerial Photograph
    • Terrain with aerial photograph, shadows and detail. Using multiple passes when texturing
  • Synthetic terrain.
    • Demonstrates using TGLCustomHDS as the terrain renderer height data source.
    • Also demonstrates 1D textures
Free Forms
  • Centering
    • Demonstrates automatically centering a freeform using the freeform autocentering property
  • BSP
    • Demonstrates loading a Quake III BSP map. Includes collision detection
  • Mushroom
    • Uses a freeform to load a 3DStudio (.3DS) mesh and uses
    • TGLProxyObject to duplicate the object.:
    • Also has fog and a textured "ground"
  • OpenBSP
    • Demonstrates OpenBSP map and also includes collision detection
Actors
  • Actor
    • Uses TGLActor object to load Quake II model (.md2) and:
    • demonstrates animating an actor (morph animation).:
    • Also displays an actor's frame names
  • Actor with two cameras
    • Demonstrates an actor from a first person and third person perspective.
    • Also demontrates moving a TGLActor (Quake II model with wepon) in a small scenery.:
    • Has doom-like (keyboard only) movement, with walk/run, turn/strafe:
  • Quake 3 Actor
    • Demonstrates a Quake 3 Actor
  • Skeletal
    • Demonstrates 3 animations for a Half Life SMD actor
  • Subdivide
    • Early mesh subdivision refinement demo using the meshutils subdividetriangles procedure.
    • Note that MD2 format isn't really suited for refinement:
Mesh Demos That Dont include Terrains and Actors

Constructive Solid Geometry

  • The CSG system uses BSP to optimize what triangles it considers.:
  • Features CSG_Union, CSG_Subtraction, CSG_Intersection.

Ducky

  • Loading NURBS into a GLScene Freeform/Actor object and then
  • using the resolution slider to increase or decrease the models triangle count dynamically.

Extrude polygon

  • Cuts a hole in a polygon

Feedback

  • Uses TGLFeedback render mode to gather vertex information
  • passed through the OpenGL render pipeline

Formula

  • Uses the TGLMesh object to plot a formula in 3D.
  • Triangle and triangle-strip meshes are used to make regular, grid-based, height-fields meshes:

Portal

  • Uses TGLPortal to render indoor scenes with a
  • basic wolfenstein-like "level designer" for generating the maze mesh:

Tiles

  • Illustrates the use of TGLTilePlane to render an area made of tiled textures placed in a grid

Tree

  • Demonstrates TGLTree with ability to change tree parameters on the form
