New CompizFusion special effects: 3D spherical desktop-general Linux technology-Linux technology and application information. For more information, see the following. 3D desktop is still a strong Linux system.
Compiz Fusion has added new special effects. Compiz Fusion provides a 3D cube desktop, which is enough to extend the distance from Vista's Aero desktop effects, but developers of Compiz Fusion seem not satisfied with this.
Previously, I ha
LinkFormula for Calculating the spherical distance: D (x1, Y1, X2, Y2) = r * arccos (sin (X1) * sin (X2) + cos (X1) * Cos (X2) * Cos (y1-y2) x1, Y1 is the unit of radians of latitude \ longitude, r extracts useful information from the disgusting string for the Earth's radius, and then sets the formula, after processing the disgusting precision, the distance obtained must be rounded down.

Very cool magnifying glass to enlarge the effect of the text, super!
Let's show you the effect chart:
Everyone run the code first try-------------------------------------effect demo-------------------------------------------
The specific code is as follows
Small partners want to achieve this cool effect, Copy the code directly, run it, and try it, or a little more innovation.
The above is for everyone to share the JavaScript text spherical
multiply the sh coefficient of the radiation degree and the sh coefficient of the illumination to obtain the final radiation degree, add the image as a parameter to the illumination model to obtain a diffuse image with a low frequency, soft shadow, or even interreflection.
Of course, the actual situation is far from that simple, especially the rotation of the sh coefficient. Currently, d3dxshrotate in d3dx only supports up to 6 levels of sh.

Teach everyone to make a simple spherical text effect, it is easy to do, more suitable for novice friends, mainly used to filter.
International practice, the effect first: want to learn to look down!
