CREATING cOLORLESS TEXTURES

[Andrew Mac]

I am trying create a hidden line rendering but wanted to incorporate shingkles for the siding, and then show various views and angles of the house. Can I accomplish this using the shingles textures and then making it with no color- This would also aplly to the roof shingles- I am trying to achieve a colorless rendered or hindden line drawing but with some of the selements of shingle siding and roof shingles

A Hidden Line drg will not display Textures.

Some people "annotate" hidden line viewports with polygons that have a hatch (eg shingle) applied to them.

another option;

If you create a Shingle texture from linework on a white background, you could apply that where you want, apply a white fill to everything else, and render in the new Open GL with lines mode. (you might have to turn the Ambient light up to make the white display as white not grey)

there will be other suggestions I'm sure

Thanks N

I guess I should not have used the word Texture- Is there nothing available in VW2008 that I can generate just line drawings that would represent shingles and then applied to the walls so i can see at any angle? Or apllying polygons and then fill with a hatch the only way?

If you want to see it in Hidden line, then I think you're cooked.

Hidden line will only draw the visible arrises of objects, IE no edge;no line.

You have RW; have you tried the OpenGL with edges option? If your drawing is complex, it will might draw faster than hidden line anyway.

mac b,

it's a round about way but here's what i do...

1

make a hidden line viewport of each elevation

2

'annotate' each viewport, making a polygon to

cover each shingled wall face, subtracting windows

+ doors from the polygon.

3

use the 'hatch' TOOL to fill the polygon with

your shingle pattern. this gives you the polygon

+ grouped lines in the shingle pattern.

4

delete the polygon and convert the group to

'3d polys'

5

cut the 3d poly group from the viewport annotation

and paste back into your model. position it just

outside your walls, 10mm <1/2"> will do....

6

repeat until you have clad the whole building this

way, i would stick them on a class that is only visible

on the elevation/3d viewport to avoid snapping/dimension

weirdness...

7

you obviously could do it directly in the model, but

it's easier to see what's going on working on the

hidden line viewport.

The only way is to create the shigles and sidings in 3d so they render in hidden line.

+ grouped lines in the shingle pattern.

The problem with the hatched poly technique is that he wants it to work from any angle.

if you read my mail further you will see

i describe turning the hatch into 3d polys,

and putting them back into the model in the

correct places, so that they WILL render from

any angle.

My bad,

so you did.
