First version Created base framework and created simple operators 2018-07-22 17:20:27 +02:00			`tool`

Improved nodes and added texture export Improved perlin noise and transform nodes. Added an export texture menu entry that exports a texture for the selected node. 2018-07-26 00:08:34 +02:00			`var scale_x`

Prepared all nodes for caching and added Image node Added Image node that can be used to import textures Renamed all get_shader_code methods to _get_shader code so a caching system can be integrated in node_base (and we can get rid of get_source_rgb and get_source_f functions) 2018-07-26 08:31:28 +02:00			`func _get_shader_code(uv):`
More nodes and load/save Added basic colorize and blend nodes Started implementing loading and saving texture graphs (most nodes need an update to support this) 2018-07-22 23:25:05 +02:00			`var rv = { defs="", code="" }`
Updated all nodes and added warp - updated all nodes (load/save support and shader generation) - added warp node 2018-07-23 22:18:43 +02:00			`if generated_variants.empty():`
Many changes & fixes... - shader updates are delayed by .25 seconds to avouid UI freeze - fixed GraphNode initialization upon loading - started obsoleting get_source_rgb and get_source_f functions - updated colorize node to use gradient - image node can now be loaded/saved - removed iqnoise node - rewrote perlin shader to support a seed parameter (seed is calculated from the node's position, so just move it to reseed) - Added voronoi noise node - updated code to use % formats instead of concatenating strings (should solve type problems in shaders) - reworked the context menu (now has submenus) - fixes in the gradient editor 2018-07-28 09:37:51 +02:00			`rv.defs = "float "+name+"_f(vec2 uv) { return perlin(uv, vec2(%f, %f), %d, %.9f, %d); }\n" % [ scale_x, scale_y, iterations, persistance, get_seed() ]`
