No collision: a static mesh can be set not to block anything. This is often used for small decoration like grass. Per-polygon collision (default): individual polygons collide with actors. Each material (i.e. each part of the Static Mesh using a separate texture) can be set to collide or not independently of the rest.
Novel texture layering system that allows different shading methods, variable resolutions and images per terrain zones. Creation of images based on brushes or procedural generation based on slope, direction, altitude, external shape files and erosion flowmaps. Transforming objects in Grome editor using 3D gizmos,
Static grass is used in scale models and miniatures to create realistic-looking grass textures. It consists of small coloured fibres charged with static electricity , making them stand on end when sprinkled onto a surface coated with glue that then hardens, holding the fibres in place.
Parallax occlusion mapping (POM) is an enhancement of the parallax mapping technique. Parallax occlusion mapping is used to procedurally create 3D definition in textured surfaces, using a displacement map (similar to a topography map) instead of through the generation of new geometry. [1]

Both GameMaker Studio and Unity provide a two-dimensional particle system often used by indie, hobbyist, or student game developers, though it cannot be imported into other engines. Many other solutions also exist, and particle systems are frequently written from scratch if non-standard effects or behaviors are desired.
Rendering of constructive solid geometry is particularly simple when ray tracing.Ray tracers intersect a ray with both primitives that are being operated on, apply the operator to the intersection intervals along the 1D ray, and then take the point closest to the camera along the ray as being the result.
Direct3D 9.0 [33] (released in December, 2002) added a new version of the High Level Shader Language [34] [35] support for floating-point texture formats, Multiple Render Targets (MRT), [36] Multiple-Element Textures, [37] texture lookups in the vertex shader and stencil buffer techniques.
