    • profileDecay

      public float profileDecay
      Profile decay of the particles in the shader, when using quads and plain ParticleSet.ShadingType.

    • colorNoise

      public float colorNoise

    • sizeNoise

      public double sizeNoise
      The noise in the size determination for particles. This only has effect if particles themselves do not provide a size. In that case, the final size is computed as clamp(body.size + rand.gaussian() * body.size * sizeNoise).

    • particleSizeLimits

      public double[] particleSizeLimits
      Particle size limits for the quad renderer (using quads as GL_TRIANGLES). This will be multiplied by the distance to the particle in the shader, so that size = tan(angle) * dist.

    • textureAttribute

      public String textureAttribute
      The texture attribute is an attribute in the original table that points to the texture to use. Ideally, it should be an integer value from 1 to n, where n is the number of textures.

    • textureFiles

      public String[] textureFiles
      Texture files to use for rendering the particles, at random. Applies only to quads.

      The shading type, for lighting the particles.

    • sphericalPower

      public float sphericalPower
      Controls how sharply the sphere edges darken (higher values = more pronounced sphere appearance with darker edges).
