when rendering a height maps i was thinking on how to do it before i could look at any tutorial i came up with this

for (X = 0; X <= Size; X += Jump)
{

for (Y = 0; Y <= Size; Y += Jump)
{
x = X + Jump;
y = Height(X + Jump,Y);
z = Y;
glVertex3i (x,y,z);

x = X;
y = Height(X,Y);
z = Y;
glVertex3i (x,y,z);
}
}

Height is based on raw file.. so after doing this i get strange stuff life.. a map and then a bunch of line crosing the map.. why is this happening ? is it due that the Size of the map is a even number ? let's consider
3-----2
|   / |
| /   |
1-----0

so if the last coord 1024 will be even where will the odd coord come so the strip completes ? [edited by - Metal Typhoon on January 21, 2003 12:26:20 PM]

r u drawing it all in one strip then it wont work try this

for (X = 0; X <= Size; X += Jump)
{
begin strip
for (Y = 0; Y <= Size; Y += Jump)
{
x = X + Jump;
y = Height(X + Jump,Y);
z = Y;
glVertex3i (x,y,z);

x = X;
y = Height(X,Y);
z = Y;
glVertex3i (x,y,z);
}
end strip
}

X <= Size; and x = X + Jump;
is this really a good idea?
