Still to come: Finding local max/min, inserting tangent planes, additional color mode based on the color box in the [Symb] view (right now it's hard to tell which function is which in multigraphs).

RE: GRAPH 3D v2.1
Hello,
look at this version. It uses directly the TRIANGLE function to do all the transform in one go, it should make it a whole lot faster... however, this is an old source dump, so you might want to modify it to add the latest refinements that you might have added. cyrille

RE: GRAPH 3D v2.1
What were your plot settings in the two example functions you used?

For the first plot, xmin and ymin were 4.1, and xmax and ymax were 4.1; zmin was 3 and zmax was 2 (I think). Zoom was 35. Rotation angles were left default. For the second plot, everything is default (Hit the [View] button and reset the app. It's been a while so the rotation angles may not be the same. Graph 3D  QPI  SolveSys

RE: GRAPH 3D v2.2 (beta)
Just posted a beta release of the next version of Graph 3D. It's marked beta because I have not tested it very rigorously. The older version 2.1 is still available.

Hi Han!
Thank you very much for sharing. It works perfectly! It is a great application that is already part of my program library A hug.

Hi Han
I agree with ArielPalazzesi, thank you very much for sharing and show how to program this nice calculator /Lars

RE: GRAPH 3D v2.2 (beta)
Great job Han. There is one issue though with changing the grid size.
I can only change it over a very small range. For example if the grid size is initially set to 15 and then I change it to 18 or 14, I get a plot error message. Other than that, the app works perfectly.

RE: GRAPH 3D v2.2 (beta)
Hi John,
You are likely seeing that message because the routine that generates the zvalues are likely running into instances where the input values are just right and end up causing an evaluation error. For example, \( \displaystyle 1\frac{\cos(x^2+y^2)}{x^2+y^2} \) has a singularity at \( x=y=0 \). So when you use an evensized grid, then you will have a domain error. You can get a bigger wireframe by using an odd integer (e.g. 49) or changing the window so that it isn't perfectly symmetric. Graph 3D  QPI  SolveSys

Cyrille,
Your app works fine on my calculator and the rotations and zooms are very fast. Very impressive and thanks for sharing! Thanks, Terje

RE: GRAPH 3D v2.2 (beta)
I think I have followed the instructions in the first post in this thread and can not find any syntax errors when I check the code,but I get a green plot screen when I try to plot Sin(X+Y). Also when I look at the NUM screen I get the X and Y values but the V3 column screen shows the word FALSE instead of a numerical value.

RE: GRAPH 3D v2.2 (beta)
A slightly different approach.
Some screenshots of upcoming features. \[f(x,y)= \sqrt{\frac{x}{\tan(.2y)}}  \cos(x) \] Notice the handling of disconnected domains for the middle graph. Also, all three graphs feature an intersecting zplane which can also be used to help users get the frame of reference when used at the bottom of the viewing box. Other features to come include tracing the surface, as well as a modeswitch to toggle between zclipping vs. translucent surfaces. Graph 3D  QPI  SolveSys

Hi Han!
This is a really helpful app showing the possibilities. I also appreciate your very helpful films. Can't await getting my prime. Many thanks!
