Title: Drawing bitmaps which are NOT necessarily facing the screen.
Post by: LuaPineapple on November 02, 2008, 06:29:38 pm

And so it came to pass that DRADIS would be drawn with nice 'n shiny DDS textures.

Alpha Channel? Check.
Texture Load & Display? Check.
3D Projection? Failed.

I've tried just about anything I can think of and have been poking around view perturbations for the last few hours, trying to get a bitmap quad to draw that WOULDN'T necessarily face the camera head on. (Apply directly to the forehead!)

Any ideas?

Rotating mesh + render to texture?

Instead of loading a "particle/glowoint/sprite", you could try a POF.

 :blah:
Could work, would work. The hackz level has gone up though. I'll try that.



(Personally I still think it's silly that we can't draw sprites which aren't facing the camera.)

I though sprites faced the camera by definition.

yep, they do. it's too much processor work to distort the image to make it otherwise.

So you could just map your bitmap to a plane and then do whatever you want with that, right?

yep, that's regular games do it. or they bake the animation to a sprite.

Why don't you draw a simple quad with the sprite set as a texture?

gr.drawSprite(texture,radius,position,orientation) ?

I'm assumeing we are talking about scripting here?

does scripting have a basic draw polygon function? if so then what you do is have four points, we will call them a, b, c, and d (they should probably be in an array) a and b are on the 'top' c and d the 'bottom' a and d the 'right', b and c 'left'

a-b
| |
d-c

now lets give the thing a radius r

all you have to do is multiply the orientation matrix's up vector by r and negative r, this will give you the up and down vectors. do the same to the right vector to get right and left vectors.

a=up+right
b=up+left
c=down+left
d=down+right

set the texture and draw those four points as a polygon.

???

profit

you know you could probibly fake it with drawTechModel()

create a ship wich is just a 2 sided plane with a mostly transparent texture of yur dradis circle. then use it to draw a tech model over the radar. this should give you those pretty little dradis lines.
