1.3.0

This is probably the biggest version release yet and is mostly thanks to the amazing work of @shadielhajj!
Thank you for doing a deep re-architecture of the PBR model and Raymarching pipeline!

Also thanks to @vade for starting the Metal translation and implementing a better color blending set of functions that account for alpha values.

Lastly thank you @sdedovic and @josephreisinger for advancing the translation to WGSL.

1.1.0

What's Changed

• WARNING! BREAKING CHANGE! most sample functions MACROS inside filter/ folder use to have only one argument (the texture coordinates). This was inconsistent to sample functions MACROS on the sample/ folder. Ultimately one single argument force the user to remember the internal name for the texture (tex) while having to two arguments (the texture and the coordinates), makes it more intuitive and consistent. So they went from being SOMETHING_SAMPLE_FNC(UV) to SOMETHING_SAMPLE_FNC(TEX, UV) 1efaad2
• Removing automatic definition of glslViewer variables and choosing a more declarative approach. For example to use the pbr() function all this MACROS pointing to the right uniforms need to be satisfy (most have correct defaults, but other defaults can't product correct behaviors.

#define SURFACE_POSITION    v_position
#define CAMERA_POSITION     u_camera
#define IBL_LUMINANCE       u_iblLuminance
#define LIGHT_DIRECTION     u_light
#define LIGHT_COLOR         u_lightColor
#define LIGHT_FALLOFF       u_lightFalloff
#define LIGHT_INTENSITY     u_lightIntensity
#define LIGHT_COORD         v_lightCoord

• Default SURFACE_POSITION to vec3(0.0) by @gzozulin in #37
• Update pbr.glsl by @gzozulin in #36
• Adding sample.glsl used by all sampling functions to support the right version on GLSL

#if __VERSION__ >= 300
#define SAMPLER_FNC(TEX, UV) texture(TEX, UV)
#else
#define SAMPLER_FNC(TEX, UV) texture2D(TEX, UV)
#endif

• Adding morphological folder for erosion, dilation, alphaFill and poissonFill.
  
  
  
• adding sample functions to fake different filter modes like NEAREST, BICUBIC, SMOOTH (by Inigo Quiles)
  
  
  
• he have been adding sample functions to fake different wrap modes like REPEAT, CLAMP2EDGE, MIRROR and UNTILE (also by @iquilezles )
  
  
  
• Adding new pbrGlass() and pbrClearCoat() models
  
  
• Adding spheremaps (or matcap) function
  
• Adding Iridescence functions
  
• New integrations to TouchDesigner implementation by @LeithBA in #28
