How to do isometric perspective in Maya?

IgnitionChemistry

Hi guys,
I'm doing a school work for descriptive geometry class, I modelled an 'M' letter in Autodesk Maya and I took the M and did a rotation then a mirror and cutted it in half, with those 3 actions I got some of the assignment done, but now I have to represent those geometries in specific perspectives like: isometric, dimetric, cavalier and other axonometrics.

Basically I have to do this:




I have to give an angle degree from the sides in order to simulate a perspective on paper, normally I do this on paper but I thought it'd be easier to do on maya, the geometries are done but I have no clue how to set up a camera for a perspective... can someone help?

Generally in 3d, the setting you are looking for is called Orthographic view and it's generally a camera setting.

Your last one is easy enough, just create a camera and then in the Attribute editor click turn on Orthographic. With a bit of math (or just fiddling with the camera) you can set it up to whatever angle you like. The others will likely have to be cheated if you want to do them in maya.

Doh.. too slow.

Hi! Thanks for replying. I got to that part, I ticked orthographic view active but I'm not sure where exactly should I place the camera and in how many angles to rotate it to get the result I want...

rube

To get the isometric view you show, start with a orthographic camera rotation of x:-35, y:45 z:0. then position the camera however you want it.. Of course this will depend on the orientation of your object.

the orientation is just a modified cube in 0,0,0... isn't isometric a 30º for each side? why should I put the -35 and 45 in those axis? just trying to understand the formula so I can do the same for the other perspectives

You could set the focal length super high. It brings up some other display errors, which are probably clip-plane problems.

rube @ it worked for isometric perspective.. now for the other perspectives I havent tried yet, but I suppose I could consider an equation and go from there... why is it x: -35 and Y: 45? Im just trying to understand why these numbers

Vertrucio

They're angles, in degrees.

rotate the camera along the Y axis 45 degrees, then rotate up the X axis by -35 degrees.

Thanks guys, the isometric perspective was cake. The other views, like military, cavalier and the rest were harder... I managed to simulate the effect I wanted with the shear control
Took the idea from a rhino tutorial and some heavy google seach!
