Cubemap generator

Despite the fact that cube maps are defined on cubemap generator spherical domain, standard cubemap mipchain generation techniques perform filtering independently on each cube face. The main problem with this approach is that no information is propagated across edges, thus creating undesirable discontinuities along the cube face edges, cubemap generator.

With the DZ format of libvips it is even possible to create tiled images of the cubefaces. When used with a glob pattern for multiple input files, kubi generates an index file once and reuses it while processing all matched images. This can lead to a significant speedup. The above would work with Marzipano :. If only a few cubemaps are needed, performance is probably of minor concern.

Also supported is a specialized DXT compressor which allows for the creation of seamless DXT compressed cubemaps cubemap generator taking into account adjacent blocks across cubemap edges during compression.

But with kubi it should also be possible to process thousands of animation frames in a reasonable time:. Both transforms are univariate and therefore very easy to implement. They both significantly reduce the distortion of the cubemap and thus optimize the pixel yield.

Cubemap generator

A Cubemap is a collection of six square textures that represent the reflections on an environment. The six squares form the faces of an imaginary cube that surrounds an object; each face represents the view along the directions of the world axes up, down, left, right, forward and back. The fastest way to create cubemaps is to import them from specially laid out Textures An image used when rendering a GameObject, Sprite, or UI element. Textures are often applied to the surface of a mesh to give it visual detail. More info See in Glossary. Select the Texture in the Project window A window that shows the contents of your Assets folder Project tab More info See in Glossary , to see the Import Settings in the Inspector A Unity window that displays information about the currently selected GameObject, asset or project settings, allowing you to inspect and edit the values. More info See in Glossary window. In the Import Settings, set the Texture Type to Default , Normal Map A type of Bump Map texture that allows you to add surface detail such as bumps, grooves, and scratches to a model which catch the light as if they are represented by real geometry. Unity then automatically sets the Texture up as a Cubemap.

In addition to this, the filtering takes into account the solid angle subtended by each tap in the filter. A limitation of nearly all cube mapping hardware which makes the seam problem substantially worse is the fact that the bilinear texel filtering is not able to fetch across cube faces thus producing a hard seam artifact in addition to introducing aliasing artifacts.

Here are some examples of the enhanced filtering and mipchain generation that CubeMapGen provides:. Contributors 2. Our publications. But with kubi it should also be possible to process thousands of animation frames in a reasonable time:. Command Line Interface: Allows you to use CubeMapGen as a command line tool for processing cubemaps in scripts and batch files. Standard cube-map filtering for mip-chain generation filters each cubemap face in isolation, and does not take into account texels from other faces.
