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,
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.
Especially grass and foliage will seem to pop-up when getting closer, also known as foliage culling. [5] LOD can also be used to render fractal terrain in real time. [ 6 ] Unreal Engine 5 's Nanite system essentially implements level-of-detail within meshes instead of just objects as a whole.
Parallax mapping is essentially a method by which rough or uneven surfaces on a 2D texture can be "pulled out" to take on the appearance of a 3D surface. Technically, this is implemented by displacing the texture coordinates at a point on the rendered polygon by a function of the view angle in tangent space (the angle relative to the surface ...
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]
Finally, a Sobel filter or similar edge-detection filter is applied to the normal and depth textures to generate an edge texture. Texels on detected edges are black, while all other texels are white. Finally, the edge texture and the color texture are composited to produce the final rendered image.
A texture map [5] [6] is an image applied (mapped) to the surface of a shape or polygon. [7] This may be a bitmap image or a procedural texture.They may be stored in common image file formats, referenced by 3D model formats or material definitions, and assembled into resource bundles.
In computer graphics, relief mapping is a texture mapping technique first introduced in 2000 [1] used to render the surface details of three-dimensional objects accurately and efficiently. [2] It can produce accurate depictions of self-occlusion, self-shadowing, and parallax. [3] It is a form of short-distance ray tracing done in a pixel shader.
