Working with triangular prims...

Has anyone out there tried building with triangular prims?

It seems to me its impossible to even create a basic triangle with three equal 10 metre sides.

If anyone is expert in building in triangles please get in touch.

Also I am continually tired of trying to build within the constraints of ten metre prims - if anyone knows of any petitions or votes to get lindens to increase the size of prims and make 'megaprims ' the norm as they are in other virtual worlds please let me know about that too.

You can use some basic trig to calculate the size needed to create an 10m equilateral. You need a box with X-axis 10m and z-axis (10 * sin 60) = 8.66025m. Full taper on the x-axis should give a 10m equilateral. Depending on the viewer you use, you might not be able to get the size with enough accuracy; the LL viewer gives you 3dp, Emerald gives up to 5dp.

Build forums might give you a better answer.

Hi Maelstrom! The height for equilateral triangles is width * (sqr(3) / 2).

I'm going to sound remarkably dense and admit that Im hopeless when it comes to mathematics...

Can you possibly make that any clearer for me..or even possibly send me a 10 metre triangle to look at in world...

Im afraid nothing I could think of could get me a ten metre shape.

Is it too much to ask for a 10 metre prism to have 10 metre sides ??

Incidentally I notice that the object info box is pretty useless when it comes to triangles as the measurements given dont relate to the sides of the triangle....

I dont suppose anyone has premade mega triangles for sale....

There are a bunch of Online calculators around

this one has pretty diagrams and no pop up ads.....

Im grateful to cerise to coming in world and proving it could be done and how to do it...

Now if only megaprims were freely avaiable as norm....

(I'll see how I go with your calculators Von thanks for the info)

Mael, I haven't tried this in world, but it seems to work on paper...

1. Make a box, 10 x 8.66 x whatever thickness you want.

2. Path cut it so it's a right triangle, with base 10m and height 8.66 m.

3. shear it so the vertex moves over the midpoint of the base, instead of over one end.

Or, alternatively,

1. Make the same box.

2. Taper it so that one 10m side goes to a point.

...and optionally poke at the shear if you want more equilateral than right-angle.

fortunately I was given ten metre equilaterals by a couple of people who are a lot better at maths than I am. Many thanks...Fortunately I can now put these together to make allsorts of bigger triangles and polygons and extend my building range beyone cuboids and spheres. I hope to get round to all the other links , calculators etc other people have provided to. Again Many Thanks.

HOWEVER - I am forced to ask why when other sites can allow not only megaprims up to 100 metres, a higher degree of shape 'hollowing' AND more prims to a region - lots more in fact - why lindens can't make moves in the same direction.

And Im wondering why we cant get a range of triangles - equilateral, isoceles whatever, plus polygons and polyhedra too...

I think moves towards not only improving but EXTENDING the tools available to builders would by a good return on the money I pay to lindens and make a change from the usual 'you can't do this, you can't do that, you must verify this ' sort of edict we seem to get nowadays....

For megaprims, I think the problem LL has with them is that they tend to lead to more abuse. LL is probably reluctant to do things that will add to their service/governance load and offiically supporting megaprims will indeed lead to more "parcel encroachment" ARs.

For different hollowing and stuff, I dunno.. I have heard that they only allow the UI to set things to 90% transparent because people used to lose prims a lot when they set them to fully transparent. Maybe it's something related to that...

For more prims, that's probably sorta a function of how much memory the sim has available to it and how they expect things to be used. If somebody has an opensim with a ton of memory and they're the only one using it, they can crank up the max prims without much consequence. LL needs to be more worried about people abusing limits and the fact that full-region hosts run 4 regions at once..

There was talk of some new server , generally to technical for me but the word as I understood it was that Lindens were going to use them to support twice the number of regions ...Id have thought it might have been a nice gesture to use improved tech (if thats what it is) to actually improve the lot of premium users who i still believe to be the ground roots of sl who pay to keep things going.

As for misuse of mega prims by griefers well you can give a 1 metre cube to a true griefer and he'll abuse it...some might say you need no more than the ability to use note cards, security orbs and ban lines to grief people so to me its like saying you can't give a gun nut a machine gun when he already has access to a hand pistol.

I more meant regular folks mistakenly pissing off their neighbors..

Do *I* think it's a good reason to not raise the prim size limit to 40m on a side? Nope! Just saying that this is what I've heard Lindens say...

40's still a bit tiny for me I like to build BIG


As for the Lindens I still have this underlying nagging suspicion that legalised megaprims which can be properly edited ( and a prim increase ) might loose em cash....

My own personal opinion is that fully editable megaprims as norm and a prim increase might lead to a more polished look in sl builds.
