Definitions

1. Texture coordinates are specified at each vertex of a given triangle, and these coordinates are interpolated using an extended Bresenham's line algorithm. (Web site)
2. Texture coordinates are specified at each vertex of a given triangle, and these coordinates are interpolated through one or more algorithmic methods. (Web site)
3. Texture coordinates are part of the data that is associated with each vertex. (Web site)
4. Texture coordinates (0,0) are the lower-left corner of the screen and (1,1) are the upper-right. (Web site)
5. The (s,t,r) texture coordinates are treated as a direction vector emanating from the center of a cube. (Web site)

Texture Plane

1. In effect, texture coordinates at the right and bottom on the texture plane are exclusive.

Texture Data

1. When texture data is needed, the texture space resampler is used to obtain a texture sample given the texture coordinates.

Screen Coordinates

1. In this chapter, we use (i, j) to designate screen coordinates and (s, t) to designate image and texture coordinates. (Web site)

Four Coordinates

1. Texture coordinates can comprise one, two, three, or four coordinates. (Web site)

Fractional Portion

1. Only the fractional portion of the texture coordinates is used; the integer portion is discarded. (Web site)

Texture Coordinates Yourself

1. It is possible to have OpenGL map the texture automatically for you, so that you don't have to define texture coordinates yourself.

Geometric Primitive

1. In general, a geometric primitive is provided, with each vertex tagged with (s, t) texture coordinates. (Web site)

Counterclockwise Order

1. When you're drawing the wall, just give those four coordinate sets as the texture coordinates as you specify the wall's vertices in counterclockwise order. (Web site)

Texture Map

1. Projective texture mapping is a technique for generating texture coordinates dynamically via a projection of 3D geometry into a (usually 2D) texture map.

Fixed

1. Also, since texture coordinates usually remain fixed for objects, any reconstruction (and triangle signal sampling) is consistent over subsequent frames.

Information

1. Texture coordinates in texture space are derived using information determined at the time of surface mesh generation. (Web site)

Default

1. By default, the texture matrix is the identity, so the texture coordinates you explicitly assign or those that are automatically generated remain unchanged. (Web site)

Assignment

1. Assignment of texture coordinates is often done in an explicit fashion (i.e., specific texture values are attached to each object vertex).
2. Note to ambitious students: I had planned an assignment here to calculate texture coordinates yourself, to map over whatever geometry you like.

Algorithm

1. Our algorithm optimizes the use of texture space by computing a warping function for the image and new texture coordinates.

Specified

1. Note that texture coordinates are specified along with vertex coordinates. (Web site)

Vertices

1. When using nonplanar color values or texture coordinates, there isn't a correct way to generate new values associated with clipped vertices.
2. Subsequent calls to glVertex*() result in those vertices being assigned the current texture coordinates. (Web site)

Different Way

1. I had to come up with a way to use only one material, and to deal with texture coordinates in a different way.

Corner

1. By default, the texture coordinates at each corner are the same as the surface parameters (s=u, t=v).

Normal Vector

1. A vertex is a position along with other information such as color, normal vector and texture coordinates. (Web site)

Texture Mapping

1. Environment mapping is a form of texture mapping in which the texture coordinates are view-dependent. (Web site)
2. Texture mapping on the GPU normally requires that objects be parameterized with texture coordinates, which can be difficult with certain types of models. (Web site)

Unit Square

1. The correspondence between these texture coordinates and the corners of the unit square is given by the following table.

Change

1. No change is made to the z coordinate of the current raster position, or to the current raster color, index, or texture coordinates. (Web site)

Current Values

1. In the first two cases, the texture coordinates are the current values of the predefined variables (s,t). (Web site)

Sets

1. Sets the texture transform object used to transform texture coordinates. (Web site)
2. Sets the current texture coordinates (s, t, r, q). (Web site)

Set

1. At the bare minimum, a texture map must be specified, texture mapping must be enabled, and appropriate texture coordinates must be set at each vertex.

Fig

1. ON the other hand, the texture coordinates shown in FIG. 6A are fixed as they are initially inputted while the cubic body is variably rotated. (Web site)

Wrapping

1. To see the effects of wrapping, you must have texture coordinates that venture beyond [0.0, 1.0]. (Web site)

Colors

1. For this reason, you're more likely to encounter this problem with colors than texture coordinates.

Range

1. When texture coordinates go outside the range of 0.0 to 1.0, they are either clamped to the surface or repeated.

Matching

1. The solution of previous problem is blending of texture colors around the matching texture coordinates. (Web site)
2. The normal map mode generates texture coordinates (s,t,r) matching the vertex's transformed eye-space normal. (Web site)

Repeating

1. During repeating, the integer part of texture coordinates is ignored, and copies of the texture map tile the surface. (Web site)

Triangle

1. As exemplified by FIG. 4, the texture coordinates are inputted to specify vertexes TA, TB and TC of another triangle. (Web site)

Opengl

1. To achieve these effects, let OpenGL automatically generate the texture coordinates for you, rather than explicitly assigning them with glTexCoord*(). (Web site)
2. To perform environment mapping, all you have to do is create an appropriate texture map and then have OpenGL generate the texture coordinates for you. (Web site)

Value

1. In addition to location values, you can specify other items for each vertex, such as a color value, normal vector, and texture coordinates. (Web site)
2. In these equations, u k and v k are the texture coordinates and y k is the color value at point k.

Values

1. The solution to this problem is to not use nonplanar color values and texture coordinates.
2. A second reason the color or texture mapping might be incorrect for a clipped primitive is because the color values or texture coordinates are nonplanar.
3. The texture coordinates at each corner of this unit square are given by providing a corresponding set of (s,t) values.

Texel

1. The texture coordinates determine which texel in the texture map is assigned to that vertex. (Web site)

Texels

1. When the texture coordinates are near the edge of the texture map, the nearest 2x2 array of texels might include some that are outside the texture map. (Web site)
2. Texels which are closer to matching texture coordinates than obtained radius, should be blended. (Web site)

Clamp

1. CLAMP - clamps texture coordinates to be in the range [0,1].

Normal Vectors

1. The points can represent vertices, RGBA color data, normal vectors, or texture coordinates. (Web site)
2. Of most interest are normal vectors and texture coordinates.

Interpolated

1. Texture coordinates are interpolated as a polygon is filled. (Web site)

Surface

1. In 3D computer graphics the position of a point on the surface of an object(not just a sphere) can be specified using its s and t texture coordinates. (Web site)
2. Normal vectors are used for lighting effects, and texture coordinates are used when applying textures to the surface via texture mapping. (Web site)
3. By the operation of the present invention, texture coordinates (u, v) are calculated for each point (x, y, z) on the surface of interest.

Normals

1. Points, colors, normals, or texture coordinates must be supplied over a surface instead of a curve. (Web site)

Textures

1. The library supports texture mapping with textures in up to 3-dimensions and automatic interpolation of texture coordinates. (Web site)

Texturing

1. If texturing is disabled, a rasterized fragment is passed on unaltered to the next stage of the GL (although its texture coordinates may be discarded). (Web site)

Texture

1. The texture transform can translate, scale, or rotate the texture coordinates before the texture is applied to the object. (Web site)
2. Also, texture coordinates determine how much texture to add when moving pieces of the texture from texture memory to the computer display. (Web site)
3. WRAP - repeats the texture by wrapping texture coordinates that are outside the range [0,1].

Coordinates

1. FIGS. 3A and 3B are schematic diagrams showing examples of fill coordinates and texture coordinates inputted into the inventive texture mapping apparatus. (Web site)
2. Importantly, the CPU 3 gives the initial values of the fill coordinates and the texture coordinates to the texture mapping unit 1. (Web site)
3. The CPU 3 freely sets the fill coordinates and the texture coordinates according to commands of a user. (Web site)
