Wishlist for 2024

(Model by Mikko Sinisalo)

Hi everyone, thanks for all the support in the past years.

Many improvements and features (Helix, Sweep, Groove Blend, etc.) have been made from the user suggestions and requests.

For some of the features, I didn't realize how to implement them at first, but finally found some workaround (tho...

MagicaCSG Feature: Discretely Sampled Spline

Added a discrete variant for swept volume mode (still optimizing the structure and ui).

Instead of continuous surfaces, it generates a series of slices along the spline based on selected C0/C1/C2 interpolation.

It has two new options:

1. slice count: defines how many slices between two adjacent control points (up to 15)

2.slice height: defines the height of each slice (triangle, hexagon, cylinder, rectangle profiles)

Bevel and round can also be applied to the sli...

How to import Sprites Animation in MagicaVoxel (0.99.7.2)

(Sample images are from the awesome game "River City Girl". Only for demonstrating purposes)

1. Drop the palette image to palette view to import palette;

2. Drop sprite images (same size, transparent png, named with frame index) to editor view and select "Import Sprites" in the menu;

3. Adjust animation frames in model space;

4. Adjust position in the world space;

[ToDo]

Use the indices directly from png color table.

MagicaCSG 0.4.3 Beta: C0/C2 Continuity and Groove Blend

I. C0/C1/C2 Continuity for Sweep Splines (on the top bar):

1. C0: polylines, linearly interpolation

2. C1: smooth tangent, cubic spline (Catmull-Rom) -> default

3. C2: smooth second derivative (smooth reflection), cubic spline (B-Spline)

Unlike C0/C1, the spline doesn't go through the control points with C2 continuity.

II. Groove Blend

The new Groove blend mode allows you to apply Boolean oper...

MagicaCSG Feature: Groove Blend

The new Groove blend mode allows you to apply Boolean operations within a certain thickness around the surface (i.e., you can use primitives to extrude the surface).

In the first image, left is without groove blend, right is with groove blend.

You can also add blend factor or fillet/chamfer blend to this mode.

If you only want to apply this on the intersected edges, you can add hole/shell to the primitive.

MagicaCSG Feature: C0/C1/C2 Continuity

Will support C0/C1/C2 Continuity for Sweep Splines:

1. C0: polylines, linearly interpolation

2. C1: smooth tangent, cubic spline (Catmull-Rom) -> default

3. C2: smooth second derivative (smooth reflection), cubic spline (B-Spline)

Unlike C0/C1, the spline doesn't go through the control points with C2 continuity. 

MagicaCSG 0.4.2 Beta: Bezier Sweep Patch

Now you can apply Sweep Mode to Bezier curves/Line segments profile to create surface patches.

- Click the control point and then modify the corresponding width and the offset of the midpoint at each control point.

- May need to manually avoid extreme twisting to reduce self intersections and cracks.

- The improvement for Bezier curve still has some bugs, so it is not included in this update.

Other Progresses

- There will be several other improvements ...

MagicaVoxel on Surface

Some simple tests on the basic features of MagicaVoxel on Surface.

Overall, it's quite relaxing to operate with one hand on the screen.

Some changes:

1.  maps the two-finger gesture to middle button/wheel. So you can use this gesture to pan/zoom camera view and ui panels.

2. enable on-screen keyboard (osk) for text field input.

3. the gizmo requires some redesign to take the lager contact area of fingers into consideration.

4. The same to the other sli...

MagicaCSG Feature: Bezier Patch

Planned to support Swept Mode for Bezier curves/Line segments to create surface patches (probably the most expensive primitive).

You can change the width and the offset of midpoint at each control point.

You may need to manually avoid extreme twisting to reduce self intersections and cracks.

Another very important progress is the High Quality Bezier Curve.

The previous implementation is based on iq's analytic Bezier sdf implementation, which is not numerical robust and...

MagicaCSG on Surface?

Bought a Surface Pro 7 to investigate the rendering issues on Intel UHD mentioned by some users before.

The program was originally not designed for tablet, so some features like gesture-based camera navigation and gizmo control are missing. And of course, the performance.

But I think I'll improve the user experience in the future, since it feels quite interesting so far.

MagicaCSG 0.4.1 Curved Boundary

The file format in this version is different from previous versions.

Please backup your old models.

1. New Curved Boundary

It can be applied to Triangle, Quad, Cube, Joint to create a smooth boundary with C1 continuity (tangent continuous).

The old muscle modifier is also combined with this option for 4-point Bezier curves.

2. Mirror X/Y/Z

Mirroring modifier now works in all axes.

Aerialod 0.0.2 Public Release

Updates in the public release:

1. Support 16-bit depth color map (will be converted to 8-bit depth image internally)

2. sRGB Color Mode: if the image is in linear color space, you may need to disable this option (like in the screenshot, the original image is too dark in sRGB color mode)

3. Linear Image Filter: if you don't want the color blurred across the borders, you may need to disable this option (like in the screenshot)

4. Save/load map/renderin...

MagicaCSG: Curved Boundary

In the next update, you will be able to apply a new curved boundary modifier to Triangle/Quad/Cube profile shapes to obtain a smooth boundary defined by Bezier curves.

Note that the Egg modifier of Joint Shape, and the Muscle modifier of Bezier curve are all merged into this modifier.

The image below shows all available modifiers to a single profile shape so far:

• Extrude
• Curved Boundary
• Revolve
• Torus
• Helix
• Cone
• Hole...

MagicaCSG: mirror

You will be able to mirror the stroke in all three axes from the new interface in the next update.

• disable all three axes by pressing the button with a mirror icon.
• Half and Rhombus (Local Mirror) modifiers have similar settings.
• can also show the local origin and axes in dashed lines.

Note that you need to put the stroke in the positive region; otherwise, the stroke is invisible.

MagicaCSG 0.4.0 Beta: Swept Volume

You can find some video tutorials in the previous two posts.

Here is some more information:

1. You can ALT+Drag a control point to insert a new control point on the path (up to 8).

2. You can press DELETE key to delete the selected control point.

3. The cost of the profiles: sphere << rectangle/triangle/hexagon << cylinder

When you encounter a performance issue, lower the resolution and decrease the number of swept volumes in a single...

MagicaCSG Demo II: Constraints of Swept Paths

The default setting provides you 4 degrees of freedom per control point for the swept path.

But the tool also provides several constraint options to make the manipulation of shape easier.

(See the Top Bar)

1. Position Constraint

1D: the control points are on the same axis (local Z)

2D: the control points are on the same plane (local YZ)

3D: free to move the points in 3D space.

2. Size Constraint

C: customized si...

MagicaCSG Demo I: Control Points of Swept Volume

1. Select Swept Extrude Mode

There are 5 extrude modes: straight extrude, revolve, torus, helix and sweep now.

Select the sweep mode, then the sweep tools will show on the top bar.

2. Insert/Delete Control Points

Click the two arrow buttons on the tool bar to delete/insert a point on the sweep path.

You can also press ALT while dragging a control point to insert a point after it.

Currently, you can have up to 8 control poin...

MagicaCSG Feature: Curved Boundary

Had several experiments recently to explore potential features in the following updates.

One of them is to add curved smooth boundary to Triangle, Quad, and Rectangle shapes, giving them a more natural appearance than just bevel/round edges. What can be created with it?

And the basic features for swept volumes are almost finished. It may be released next month for testing. I'll record some demo videos to introduce the new tool sets.

MagicaCSG New System: SDF of Swept Volume

Hi everyone, a new powerful and expensive editing tool will be added to MagicaCSG:

    "The SDF of Swept Volume",

which is defined by the space of a shape swept along a spline.

It has the following properties:

1. Cubic Spline (C1 Continuity)

2. Various Profile Shape (Sphere, Cube, Triangle, etc.)

3. Varying Size and Orientation for each Control Point

4. Mor...
