Support / Align camera perpendicular to an object
« on: August 11, 2014, 10:45:38 am »

I have a "floor" for my scene made of 800 triangles that are doing a big rectangle. Always i are trying to align the camera manually, but i want to know if there is a method for align the camera on 90 degrees over my object and center. is it possible?

Thank you very much.

Support / Draw 3D Terrain with planes and change it on real time
« on: July 07, 2013, 05:46:09 pm »

I'm looking for the best way to draw a small grid of planes (for explample 10x10) that looks like a simple big rectangle with a texture from image, but i want to move it on real time, the vertex of each plane (join with nearest plane) would be move. I want to do an physical effect like waves or other over this grid.

¿how is the best way to implement this 3D objects and move it?

I try to create on each iteration all 100 planes, but it is very heavy, i'm seeing with ClientFactory to do like a 3d terrain, but ¿how can i move the vertex of planes on realtime, move deforming his form makes trapezoid and the plane doesn't keep the same size or square form.

i hope you can understand my english, sorry for that and thank you in advance.

Support / Apply texture image to cylindre

I have created an object3d from Primitives.getCylindre(...) and i want to apply my texture from image file. ¿how i must do it? ¿what are the uv coords of cylindre objects? ¿have you any example?

Thank you in advance.

Support / light and material effects for newie

First of all, thanks a lot for this great engine, i have working with it for some days.

On my little example i'm trying to show an Object3D (sphere in this case) and practice various effects, and unfortunately i can't do very much. Please, could somebody teach me how to make the following effects? or unless link to gl tutorial or something?

- partial transparency, ¿how it is possible to see the other side of the object? when i apply transparency i see the background but not the other side of my object3d.

- light or material effect. i'm trying to make an pullid and brightness effect to my sphere, like a billiard ball.

thank you in advance.
