GRAPH 3D v2.425 (20-FEB-2017)

[Jedidiah Smith]

Hi Han, thank you for this great program. I finally had some time to install and tinker with it a little on my daughter's HP Prime. Then we compared it to plot times with the Wireframe Plot setting on my HP RPN graphing calcs. All running latest firmware where applicable.

Equation & plot window setup from the Wireframe example in the HP48G Manual: X^3*Y-X*Y^3.

0.1 Sec = HP Prime running Han's program Ver 2.422
3 sec = Samsung NoteII (ARM A9 quad core 1.6GHz) go48g emulator at 10X speed
4.3 sec = Samsung NoteII (ARM Cortex A9 quad core 1.6GHz) Droid48 emulator
6 sec = Motorola Atrix HD (Snapdragon S4 Krait dual core 1.5GHz) Droid48 emulator
23 sec = HP 50G
23 sec = HP 49G+
25 sec = HP 48GII (Second version)
61 sec = HP 48G+
78 sec = HP 49G

Amazing result. As an HP48G series diehard, I am now thinking of getting the Prime for myself. If I do that, the others are just going to sit there though...one could get used to this speed! ;-)
