6.3 Element to support a ray marching algorithm

<Raymarch /> is a special element that creates and renders a signed distance function using the ray marching algorithm, similar to shadertoy. *NOTE: This element is unfortunately not included in the current version as it requires a number of shader sources and image files. It will be released as an addon to threefy soon.

<Raymarch
    vshader={vertexShader.glsl}
    fshader={fragmentShader.glsl}
    uniforms={uniforms}
    defines={defines}
    textures={[ textureURL1, textureURL2, … ]}
/>

Here vshader and fshader refer to GLSL code. If not set, the following default GLSL codes are used.

// vshader default
void main() { gl_Position = vec4( position, 1.0 ); }

// fshader default
void main() { gl_FragColor = vec4(0.0); }
