Redshift normal map c4d

The Redshift Bump Map node supports both height maps for bump mapping and object space or tangent space normal mapping. The resolution of the these textures are important — you ideally want a one pixel per texel maximum resolution to get the best visual results.

Magnifying the texture will blur the results and minifying will lessen the effect with distance. Bump maps are controlled by a height map texture which is used to perturb the surface normal.

Since only normals are perturbed, not geometry, it does not affect shadows. Bump maps do not contain directional information. Normal maps are controlled by a 'normal' texture which is used to perturb the surface normal. Normal maps contain directional information. If set incorrectly, normal mapping will not work properly. This enables the bump map effect. When this is disabled, the normal that is generated is just the surface normal. Object-Space Normal maps contain normal information specific to the object it should be applied to.

In Object-Space the up axis is directly tied to the up axis of the object itself and therefore using an Object-Space Normal map on any object other than the one it is intended for will not look right. Tangent-Space Normal maps contain normal information that can be applied to any object and behave properly. In Tangent-Space the up axis is relative to an objects surface normal and therefore using a Tangent-Space Normal map on any object will behave correctly. Below is a comparison of an object-space normal map and a tangent-space normal map.

First the object-space and tangent-space maps are demonstrated on their intended source geometry, both look perfect. In the second example the same shader is applied to a flat plane which is where you can see how the object-space normal map perturbs the plane's normals in such a way that it does not look good. Comparatively the tangent-space normal map looks much better since it is relative to the surface normals of the plane. This scales the height value that is read from the texture.

A value of 0. Greater values increase the bump effect. Negative values invert the direction of the bumps. The default is 0. Because this is a visual trick, very large values will not yield good results, so in those cases you should use displacement mapping instead.

This option forces the resultant bump vector output to scale along with the objects scale. Disabling this option will essentially remove any scaling bias, yielding more predictable results when blending bump maps and normal maps. When this is the case, the normals will have been pre-biased to fit into the 0. This allows you to flip the Y axis of the normal map.

This is useful if the normal map was generated using a flipped uv coordinate system. In the examples below note that the lighting has not changed but where the specular highlights appear on the sphere has been inversed.

It is controlled by a 'normal' texture, which is used to perturb the surface normal.

Since only normals are perturbed, not geometry, it does not affect shadows. The resolution of the normal map texture is important — you ideally want a one pixel per texel maximum resolution to get the best visual results. Magnifying the texture will blur the results and minifying will lessen the effect with distance. When this is the case, the normals will have been pre-biased to fit into the 0.

Check this option only when you know that the texture map is unbiasedmeaning the normals were floating point and stored in the This allows you to flip the y of the normal map, which is useful if the normal map was generated using a flipped uv coordinate system. This allows you to scale the resultant normal from the normal map, yielding a stronger 'bump' effect. Texture Space This is the texture mapping space, which defines the uv channel.

This is the channel for the pre-computed surface tangents, since normal mapping is always calculated in tangent space. This gives you extra options for filtering and defined the texture coordinates. For examples, see 'Image Sampler' document.

This specifies the maximum eccentricity for elliptical filtering. The higher the value the better the results, but at the cost of performance.

A value of 1. This controls the repetition of the texture coordinates. Normally a texture is mapped with values 0. A 'Texture Repeat' value of 2. Values lower than 1. This example shows an un-textured surface, with a diffuse and glossy reflected spherical area light. Now the same scene but with the normal map applied you can see how dramatically a normal map can increase the lighting detail without paying for the extra polygons.

The trouble with this technique is that the shading on a particular texture would often be at variance with the perceived sources of light in the scene in which they were used. For example, a texture might be drawn as if it were lit from the upper left, but in a particular scene, the actual light source may be from the right, or below the texture. The color map and light map combined on a surface in a game engine. Although the surface is realistically shaded by the light map, highlights and shadows on the texture ignore which direction the light is actually coming from.

A color map that has no intrinsic shading property.

A height map that encodes the distance of the geometry from the camera as shades of gray. A new technique was developed, generically called "bump mapping".

In its simplest form, a texture on a surface contains two textures - a color map and a second map that contains the height information for the surface.

A height map would be a gray-scale image that encodes height information as shades from black the lowest to white the highest. The game engine is able to use this height map to render highlights and shadows on the surface according to where the lights in the scene are located, resulting in a vastly improved surface realism.

The color map and height map conbined in a game engine. The height map allows the game engine to render the surface as though it has been illuminated by the light source in the game. Highlights and shading appear coming from the correct direction. Because of the limitations of this technique, the resulting surface appears flattened and lacking in richness.

There is a limitation to simple height mapping techniques - the game engine is restricted to portraying transitions in elevation only, resulting in a flattened appearance of the actual height information the designer is trying to convey. Fine details get blurred out of the bump map render, because a single pixel contains no real data of its own - it is only in relation to its neighbors that it has any meaningful information. A game engine looking at a height map has to take a sample of a certain radius around each pixel to determine if this pixel is the same relative to its neighbors, or sloping up, down, to the left or to the right, before it can rendering the shading on that surface.

This sampling slightly degrades the detail that can be portrayed with the height map. A normal map of the texture geometry. The red channel encodes X horizontal vector information. The green channel encodes Y vertical vector information. The blue channel encodes Z depth vector information. Enter the "normal map". While a height map only contains 1 plane of information - the "Z" height plane, a normal map contains 3 vectors of information - "X" direction, "Y" direction and "Z" direction.

Thus, each pixel in a normal map encodes which direction that particular point is facing - the "normal vector" of the surface. Each pixel in a normal map has meaningful information, so details can be rendered more crisply than with bump maps alone. This allows modern game engines Doom III to more realistically portray the lighting on a surface.

A properly constructed normal map can fool the eye into perceiving much more complex 3D geometry on a simple surface.

Theoretically, normal maps on a cube can make it appear spherical, at least in terms of shading properties the outline remains unchanged.
