GPU render variations and caveats

Thanks Tracy for all your efforts. We all appreciate this info! This is from Tracy Colello:


arch, auger, bent, bent2, bipolar, blade, blob, blur, boarders, bubble, butterfly, cell, conic, cos, cosh, cosine, cot, coth, cpow, cross, csc, csch, curl, curve, cylinder, diamond, disc, disc2, edisc, elliptic, escher, ex, exp, exponential, eyefish, fan, fan2*, fisheye, flower, flux, foci, gaussian blur, handkerchief, heart, horseshoe, hyperbolic, julia, julian, juliascope, lazysusan, linear, log, loonie, modulus, ngon, noise, oscilloscope, parabola, pdj, perspective, pie, polar, polar2, popcorn, popcorn2, power, pre_blur, radial_blur, rays, rectangles, rings, rings2, scry, sec, secant2, sech, separation, sin, sinh, sinusoidal, spherical, spiral, split, splits, square, stripes, swirl, tan, tangent, tanh, twintrian, waves, waves2, wedge, wedge_julia*, wedge_sph, whorl.

No camera angles, no rotating triangles on zx or zy planes, no post symmetry tab, no pre or post (except preblur), some combinations of variations don’t work in the same transform (for example, two arches in the same transform does not work). Only one final transform can be used (and its color speed needs to be set to 1 for the colors to match the preview). Only one layer. Black background only, no background pictures. Single-color background setting has an odd effect on the colors but the background is still black. Linking transforms works great. fan2 works, but with continuous lines instead of choppy. wedge_julia works, but has a mirrored look. What doesn’t work is generally newer variations or those that end in 3D, wf, bs, or q.

Thanks for that. Need to absorb info!
