Still can't figure out how to get orthographic projection working, but I did have a play with the ClipPlane functions....

This is a single entity being sliced into 4 sections with each slice being rendered in a different colour.

code:
[lua]
function ENT:Draw()

if( !self || !self:IsValid() || !self.PieSections ) then return end

local selfPos = self:GetPos()
local start = 0

render.EnableClipping( true )

-- Draw each pie section.
for _, section in pairs( self.PieSections ) do

local change = section.ratio * 360
local finish = start + change + 180

local norm1 = Angle(0,start,0):Forward()
local norm2 = Angle(0,finish,0):Forward()

local dist1 = norm1:Dot( selfPos )
local dist2 = norm2:Dot( selfPos )

local r,g,b = section.color.r/255, section.color.g/255, section.color.b/255

-- First cut
render.SetColorModulation( r,g,b )
render.PushCustomClipPlane( norm1, dist1 )

-- If the change is more than 180 degrees then we need to do some voodoo
if ( change > 180 ) then
self:DrawModel()
render.PopCustomClipPlane()
end

-- Second cut
render.PushCustomClipPlane( norm2, dist2 )
self:DrawModel()
render.PopCustomClipPlane()

if ( change <= 180 ) then render.PopCustomClipPlane() end

-- Start the next section where this one finished off
start = start + change
end
end

ENT.PieSections = { { color = {r=r,g=g,b=b}, ratio = float }, { ... } }

-- Ratio is a float between 0 & 1 representing the amount of pie the section should take up.
-- You can have as many sections as you want but ideally the sum of all the ratios will add up to 1.

Can I have the green piece? :D

How many times is the model rendered just to do that?

[QUOTE=haza55;18986975]Can I have the green piece? :D

Equal to the number of slices, and once extra if one of the slices is more than 50%.

What is this in the picture actually? Cloth physics?

That it is.

[QUOTE=Jinto;19102045]That it is.[/QUOTE]

Holy shit...

Would you mind telling us how you've managed to do that..? :biggrin:

(It's funny that I ask this ~1.2 years after you posted that picture.)

It's a point mass system. Uses verlet integration and constraint relaxation. Then a mesh is drawn between the points in the system.

Seems extremely fluid, how many points lay between the cloth, and it's not expensive is it?

[Jinto]

That image with the green ribbon is a 128 x 4 system.
Plain lua can't really handle it. It's not a speed issue so much as the garbage collector can't handle it. The garbage collector is extremely inefficient. All of these were done using a binary module.
My video of the flags had no decrease in frame rate. I haven't profiled the code yet, but it doesn't look bad as it stands now.

I assumed as much, excellent work, I might add.

[maurits]

Woa that's interesting. Thanks for your info.

I have just a little more tweaking to do, then I'll release the update.[/QUOTE]

Jinto i'm still curious as to how the colouring is done in that?

[QUOTE=Hanfie;20718065]i cant donwload it ??????!?!?! can you upload it to gmod.org? pls[/QUOTE]
It's included in garrysmod default, and from your spelling, I dont think you can figure out how to use it just yet anyhow.
