OpenGL ES - set the width, height, depth of an object in 3D
I would like to ask about OPENGL ES for android, I want to build a wall with specific width, height, and depth :
public void buildingW(float width, float height, float depth)
in order to place into my program, anyone can suggest me the ideas how to do this ?
Is there anyway to build one obj file then read it ? or we can draw it directly?
Thank you very much!
One way to construct a wall is to define a cube of unit size (ie 1x1x1) with its center at the origin. Now you can draw any wall by apply a scaling, rotation and translation matrix to the mesh for the cube and them render it.
