Subject: [DirectPython] 3d Text
Hello,
I was hoping you could help me. Is there a way to create 3d Fonts from
fonts located on ones computer? I see that there are numerous examples of
2-d text. If you can create 3d text is there a way to access the vertex,
texture, and normal coordinates (x,y,z).
Any help would be great. Thank you in advance.
Regards,
Andre O'Brien
It is possible from DirectPython 0.6 onwards. I'll post a little example:
font = d3d.Font(u"Arial", 20)
textmesh = d3d.StaticMesh.fromFont(font, u"Your text goes here")
vbuffer, ibuffer = textmesh.getBuffers()
#Take a temporary copy
tempvb = vbuffer[:]
for i, vertex in enumerate(tempvb):
#Go through all vertices
tmp = list(vertex)
tmp[0] += 1.0 #Modify x
tmp[1] += 1.0 #y
tmp[2] += 1.0 #z etc.
tempvb[i] = tmp
#Copy temporary list back to the real buffer.
vbuffer[:] = tempvb
This little snippet moves each vertex 1.0-units to all (x, y, z) directions.
You can modify other attributes too, normals would be located at tmp[3-5].
Text meshes have not texture coordinates so you cant access them (unless you
generate them in a shader, but that does not really count). Note that this
is pretty inefficient, vertex shaders are usually used to modify geometry
like this. Of course if you are only generating the data once or modifying
it few times it is ok.
