sitting pic shows what happens when you stroke out the "//track back to get better resolution" part in the shader code.. not recommended, but tweek..you can **
@Number6 thanks for the support re reflections. However drat!~!..that Cave shader I was dearly hoping, would cut down on the GPU load because it has so much shadow..
Not to worry..our short-winged friend no doubt can/will throw some more light on this ..said he might be away for couple of weeks during last visit, and I'll be gone next week so won't know if there is a solution... I know the Cave does two passes (on the same thread?) ~one to render (above pic), and another pass to fill each alternate 'slice' of the scene where there is no produced graphic and its this progression within the main (void) and how it's handled which could be the problem. but TheCave they say on the shadertoy website is based on old-school programming & like you, I'm tweaking around the edges just to see what it does, more than acheiving any further outcomes atm. Awaiting more ideas ;-)
**Edit: Well there are outcomes a plenty once you stroke-out the const float ShadowIT=15.0 line and the rest of..//shadow calc below
//for (float x=1.0; x<ShadowIT; x++)
// if (Dist2D(Pos+ld*(x/ShadowIT))<threshold)
// {
// lv=0.0;
// break;
// }
I'm really happy with outcome now Unfortunately the rest I've done since, probably demands uber GPU
float fade=32.0; // increased to 32.0 from 0.0 this makes everythng smoother ~ET
const float numit=128.0; //raymarch precision. better detail throughout.~ET
const float threshold=1.20; //defines the thickness of tunnels
const float scale=2.0; //
The ***** blobby shadows are gone & the route lights up everywhere.
New paths by uncommenting & tweeking the below ~ETc
lp=Position3D(time+0.2,lighta,lightb,lightc,lightd);
the more one tweeks, the better is possible, depends on GPU ofc.
First RULE of Tweeking:..... Copy & Rename the shader
Second RULE of Tweeking..... Copy and Rename the Scene file
Third RULE ....THEN.. Tweek away on these new copies ONLY
