S3d.au3

This UDF enables you to draw simple 3D graphics.

Features:

Simple and easy to use
Doesn't require external libraries. You don't need OpenGL or DirectX.

Nice work. If you set smoothing for the gfx handle it looks much better

Func _S3d_SelectGraphic($hGraphic, $iWidth, $iHeight)
    $__S3d_hGraphic = $hGraphic
    $__S3d_iWidth = $iWidth
    $__S3d_iHeight = $iHeight
    _GDIPlus_GraphicsSetSmoothingMode($__S3d_hGraphic, 2)
EndFunc ;==>_S3d_SelectGraphic

Using matrices to rotate the object is cool. :thumbsup:

UEZ,

Thanks for the advice.

Using matrices to rotate the object is cool.

I'm going to write some examples to show the power of Local Matrices.

This looks like something I can use.

I have a small program for editing meshes but it lacks a preview feature and have to use another program to see my results.

It is able to draw UV stamps for the models using GDI, so it shouldn't be too different to adapt to this.

This looks approachable. Thanks for sharing. I'll be back with results after trying it out.

UPDATE

New version (v1.1.0) released!

Please see the first post.

Added: _S3d_RegPolygon, _S3d_Star
Added: _S3d_LocalTranslate, _S3d_LocalScale, _S3d_LocalRotateX, _S3d_LocalRotateY, _S3d_LocalRotateZ
Added: _S3d_SelectGraphic sets smoothing mode for Graphics object
Changed: default value of $fFill in _S3d_Square changed to True

Enjoy!

Starg · July 26, 2013

UPDATE

New version (v1.1.1) released! Please see the first post.

Added an example of _S3d_Star function.

Any comments are welcome.

Using floating point calls gives the movement more smoothness:

Enjoying this.

I have a question about _S3d_SetCamera()

I am drawing a wireframe of a mesh using a vertex list and a triangle list. ( _S3d_Line() works perfect for this. )

But I am having trouble positioning the camera.

_S3d_SetCamera() accepts $position_x, $position_y, $position_z and $target_x, $target_y, $target_z

Target is behaving exactly how I expect it to.

But when changing the position values, it seems to be rotating the view instead of translating.

Local $position_x = $Model_Width / 2
Local $position_y = $Model_Height / 2
Local $position_z = $Model_depth * 2 ; guessing
Local $target_x = 0
Local $target_y = 0
Local $target_z = 0

_S3d_SetCamera( $position_x, $position_y, $position_z, $target_x, $target_y, $target_z )

I expected this to put the camera at roughly the center of mass in the x/y plane and some amount out along the z plane, looking at the mesh's feet (which are at 0,0,0.)

Instead it is below and somewhere behind the origin.

I am assuming x is left-right, y is up-down, and z is fore-aft.

Is this correct?

And do the position values translate or rotate? Or am I missing something completely.

(attached a pic to show that it is indeed drawing.. which I find to be very cool.)

I am assuming x is left-right, y is up-down, and z is fore-aft.
Is this correct?

By default, z is up-down.

And do the position values translate or rotate? Or am I missing something completely.

To translate the view, you need to change both Position and Target.

Example:

_S3d_SetCamera(500 + $i, 200, 300, $i, 0, 0)

tirpider · July 27, 2013

I'm glad it was just a difference of axis alignments. I can accommodate that by just switching how I load the data from the vertex list.

I started playing with the target values (instead of leaving them at 0) and the camera view began behaving as expected. Thanks for clearing that up.

I intend to use this as a wireframe preview for a little mesh editing tool. It's just enough to help identify pieces and features within the model (that's all that is needed.) Once I have a cleaner implementation of it, I'll post an example of the code that uses your functions here.

Thanks again for putting this together. I have ideas for working with 3d models, but am terrible at the math behind it.

UPDATE

New version (v1.1.2) released! Please see the first post.

_S3d_Arrow and _S3d_Square now work even if some of the points (one for _S3d_Arrow, up to three for _S3d_Square) are behind the camera.

If you have written some example scripts that use S3d.au3, feel free to post them here.

Could you add an array that stores all the drawn objects so when I call _S3d_SetCamera() it redraws all the objects

Thanks for the suggestion. I think making a wrapper for it is better than changing S3d itself.

Thanks. I'll try it.

I found that a few months ago, but thanks anyway.
