Where did triangle strip go?

[pvloon]

Hi,

Seems that unity 4 RC 3 removed MeshTopolog.TriangleStrip? What the? I need it though, luckily, MeshTopology.Triangles + 1 does the same thing. It’s weird though!

Best regards,

No news on this?

Sorry, hate to bump this, but I’m just finding this really odd. Where did it go? Can I still safely use it using the MeshTopology.Triangles + 1 trick?

really? no one knows?

i am considering just building my own index in standard triangles…
this is quite lame that it just disappeared without suggested solution.

i wrote this to build my triangle strip…

public static int[ ] StripToIndex(int start, int length, bool flip)
{
// ignore those that can’t form a triangle
if(length < 3) return new int[0];

// calculate number of index needed for given length
int total = (length-2)*3;
int[ ] index = new int[total];

// loop all triangle to create index list
int count = 0;
int max = 0;
//bool flip = false;
for(int i=2; i<length; i++)
{
// to ensure all triangle are clockwise,
// triangle strip alternate between the points.
// we emulate this opengl behavior with the following codes.
if(flip)
{
index[count] = start+i-1; count++;
index[count] = start+i-2; count++;
}
else
{
index[count] = start+i-2; count++;
index[count] = start+i-1; count++;
}
flip = !flip;
// last point is always latest point.
max = index[count] = start+i; count++;
}
return index;
}
