Excellent! The array method work very well and allowed me to eliminate some nodes.

EDIT

I have uploaded two compounds in the ICE Compound area: DB_Cube_V1 and DB_Cube_V1a

Hope you like it!

Cheers!

Wow, that was quick. Thanks everyone for your replies. I did look at the repeat, repeat with counter, while and while with counter, unfortunately all have an execute output port which is incompatible with the slice and keep polygons node which take an array as input. It look like the array solution ...

Hello ICE Gurus, I have this piece of ICE tree that need to repeat based on an integer value input. It repeat between the add node and the scalar to vector node, with each iteration feeding a value to an array. In code that would be easy: var u = 4; var x = -.05; for (i=1, i <= u-1, i++) { x = x + 1...

Interesting compound Chris, thanks for sharing. I see some potential for texturing like skyscrapers, Kids blocks and other shapes that can be used for commercial work and advertising. For the text, letters can be defined proceduraly like any polygons in ICE. For now, this is a long process unfortuna...

Hi Chris, good work so far, looking good.

I made a small modification to your ice tree, the section that collect the old points and feed the new points. For consideration and testing.

Cheers!

You can also download the file at RRay.de http://rray.de/xsi/.

You can now create a cube at any size in various real world units.

If you want, you can clean up the mess and expose only what you need.

Next step, adding subdivisions (U,V base) to our cube.

Until next time, Happy Coding!

Using the newly create Units compound, I modified the second Cube ICE Tree as below.

So far so good. We now have a cube that we can scale at will in length, width or height. The cube is a very useful primitive. I use the cube often as a container for simulation or as an object to compare and scale other objects. One thing is missing: real world measurement. With ICE, this is easy to...

And another example, this time we drive all the parameters x,y,z (I like it better that way, although it make a mess of the ICE Tree). The cube is now centered at the world coordinate much like the Softimage primitives.

Feeding the vertex via a string node is cool but not very intuitive. The next step is to build the cube dynamically by feeding it with three scalar inputs: Length, Height and Width. Using scalar and, scalar to 3D vector nodes, we can control the size of our cube interactively in length, width and he...

Each face quad is terminated by the negative -2 indicating to Softimage that the quad definition for that face is complete and the next set of vertex indices defines the next face quad of the cube. You can change this to be triangle if you wish following the same process. With headlight turned on, w...

The next figure shows details of the String of vertices feeding the vertex position and the String of vertex ordering (CCW) defining the polygonal description of the cube. I created the vertices and the faces in the same order as the existing SI cube. To create the vertex / edge / face structure of ...

I made a quick ICE Topology tutorial and posted it at the Area and XSI Base. I promise I would post it here too so here it is. Our first ICE topology mesh is the unit cube. I have created two versions: one with the first vertex located at position 0,0,0 (which make it centered at 0.5, 0.5, 0.5) and ...

Thank You for the post, Hirazi Blue.

Very much appreciated.
