Soft particles

[AggrorJorn]

Is there a existing way to create soft particles?

 

current setup with default shader.

Perhaps you could program it yourself ?

 

uniform sampler2D colorMap;

02 uniform sampler2D depthMap;

03

04 varying float depth;

05

06 void main() {

07

08 vec2 coord = gl_FragCoord.xy / vec2(640,360);

09 vec4 depthMapDepth = -texture2D(depthMap, coord).z;

10 vec4 color = texture2D(colorMap, gl_TexCoord[0].st);

11

12 float scale = 0.2f;

13 float fade = clamp((depthMapDepth.x-depth)*scale, 0.0, 1.0);

14

15 gl_FragColor = vec4(vec3(color),color.a * fade); 16 }

What are soft particles?

[AggrorJorn]

The image on the left is the current situation. On the right you see soft particles.

Ah.

As YG suggests, we could, but would need depth information sent to the particle shader.

Why it's not possible in LE3 ? no depth info possible ?

(It's not very new technique)
