Hello,
I just started with Houdini, and tried to make a sweep kinda thingy with VEX (part of a larger plan). I cannot seem to figure out how to get around this problem. When I scatter points around my existing point, they are not rotated, I assume because the points I drew have no normal whatsoever. I want them like the red lines in the attachment.
I tried to do a lookat from one point to the next, but I cannot figure out what to do next.
//define variables
float twopi = 3.14159 * 2;
float theta = 0;
float step_angle = twopi / (float)85;
float x, z;
vector pos;
matrix n;
// define line rotation
// add points
while(theta < twopi)
{
x = @P.x + cos(theta) * .05;
z = @P.z + sin(theta) * .05;
pos = set(x, @P.y, z);
addpoint(0,pos);
theta += step_angle;
}
Any help would be appreciated.
