Hi all I am trying to do and learn some maya api (I have zero knowledge of
them)
The following code was taken from an example that I have read online and
while testing it out, I have a few questions in mind..
1. In that test() function, as the world_pos variable is calling out to the
Point class, how would I know which of the 4 functions in class Point it is
trying to call from?
2. Also, I tried to insert a print statement to show me what type it will
return by using type(world_pos), it give me result <class
'spPaint3dContext.Point'> as I was expecting results such as dict, list
etc. Then when I insert it into the functions within class, it is telling
me that it is part of MVector etc..
So, is that any ways that I can expect it to tell me similar like dict/list
etc?
class Point(object):
def __init__(self, x, y, z):
self.x = x
self.y = y
self.z = z
def asMPoint(self):
return om.MPoint(self.x, self.y, self.z)
def asMFPoint(self):
return om.MFloatPoint(self.x, self.y, self.z)
def asMVector(self):
return om.MVector(self.x, self.y, self.z)
def asMFVector(self):
return om.MFloatVector(self.x, self.y, self.z)
def test(v1, v2):
...
...
click_pos = om.MPoint()
world_pos = Point(click_pos.x, click_pos.y, click_pos.z)
# Suppose the following values for click _pos x, y and z...
# click_pos.x : -13.2409
# click_pos.y : 44.7756
# click_pos.z : -66.3071
This is a bit off-topic but I have this function where it has '2' return
variables but they are controlled by this 'smooth' parameter.
The reason that this function was wrote it this way was due to a checkbox,
thus if it is checked - smooth = True, unchecked - smooth = False
Was wondering if this is an acceptable way for me to write it this way?
def getNormal(self, smooth = False):
if smooth:
normal = om.MVector()
fn_mesh = om.MFnMesh(self.dagMeshTargetSurface)
fn_mesh.getClosestNormal(self.hitPoint.asMPoint(), normal, om.MSpace
.kWorld, None)
return normal
else:
hit_facept = om.MScriptUtil()
om.MScriptUtil().setInt(hit_facept.asIntPtr(),self.hit_face)
itMesh = om.MItMeshPolygon(self.dagMeshTargetSurface)
itMesh.setIndex(self.hit_face, hit_facept.asIntPtr())
triVertsArray = om.MPointArray()
triIndexArray = om.MIntArray()
itMesh.getTriangle(self.hit_triangle, triVertsArray, triIndexArray,
om.MSpace.kWorld)
return self.getCrossProduct(triVertsArray[0], triVertsArray[1],
triVertsArray[2])
