czm_antialias
Procedural anti-aliasing by blurring two colors that meet at a sharp edge.
Parameters:
| Name | Type | Argument | Default | Description |
|---|---|---|---|---|
color1 |
vec4 | The color on one side of the edge. | ||
color2 |
vec4 | The color on the other side of the edge. | ||
currentcolor |
vec4 | The current color, either color1 or color2. |
||
dist |
float | The distance to the edge in texture coordinates. | ||
fuzzFactor |
float |
<optional> |
0.1 | Controls the blurriness between the two colors. |
Returns:
vec4
The anti-aliased color.
Example
// GLSL declarations vec4 czm_antialias(vec4 color1, vec4 color2, vec4 currentColor, float dist, float fuzzFactor); vec4 czm_antialias(vec4 color1, vec4 color2, vec4 currentColor, float dist); // get the color for a material that has a sharp edge at the line y = 0.5 in texture space float dist = abs(textureCoordinates.t - 0.5); vec4 currentColor = mix(bottomColor, topColor, step(0.5, textureCoordinates.t)); vec4 color = czm_antialias(bottomColor, topColor, currentColor, dist, 0.1);
