sprite kit - SpriteKit + iOS8. Does SpriteKit support "baking" rendered results? -


i implementing paint program in spritekit , super impressed simplicity of implementation sprikekit enables. very cool indeed!

each brush stroke implemented skspritenode attached skshader. works expect.

issue: steadily growing skscene graph brush strokes appended. not scalable solution resource consumption mushrooms , framerate slows crawl. so, want "bake" skscene graph after brush stroke painted.

i tried setting myscene.shouldrasterize = yes on skscene instance appeared have no effect. how "bake" rendering results in spritekit? have roll own?

thanks,
doug

the can think of call texturefromnode on skview passing in sknode want "bake". take texture, apply skspritenode, , remove sknode(s) "baked" in texture.

Image
i looking create highchart multi-colored line. if goes down under value, become red, , when comes on value, become green . here picture example: or maybe highcharts have other charts models differentiate high or low level color? you can achieve coloring using lineargradient coloring: color: { lineargradient: { x1: 0, x2: 0, y1: 0, y2: 1 }, stops: [ [0, 'red'], [0.25, 'yellow'], [0.50, 'green'], [0.75, 'yellow'], [1, 'red'] ] } here 0 in stops relates minimum value of series , 1 maximum value, , in between percentages between values. if find percentages according values prior creating chart use correct stops values make relate specific values in data (at least approximately). see this jsfiddle example .
