Does MagicaCSG Support Importing Meshes?

I received many suggestions about importing meshes into MagicaCSG for reference.

The rendering engine in MagicaCSG only supports rendering SDF so far, so is it possible?

The answer is yes. Here are some screenshots from my early experiments.

You can choose the import resolution and create instances as well (image 1 and 2).

The current issue is that it's not robust and scalable for hi-res meshes and problematic meshes (non-watertight, non-manifold, etc.) , and it will c...

MagicaCSG: Advanced Polyline and Bezier Curves

Polylines and polygons are unified in the next update with new UIs.

1. they are using the same set of control points.

2. polygons can be convex, concave or self-intersecting.

3. they can be defined by either straight lines or Bezier lines.

4. straight line can also have tapered sizes (including revolve modes).

5. revolved polygons are solid now (revolved curves only have surfaces).

There will be more advanced features in 0.6.x to make more general shapes. 2024-10-19 03:20:27 +0000 UTC View Post

MagicaCSG 0.5.3 Update: Partial Radial Array and Local Rotation

Updates

You can redownload the updated program from last post.

Settings for array duplications are changed. If you have already used this feature in your projects, you may need to readjust the stroke properties. Sorry for the inconvenience.

Pros of Array Duplication

• Changes are nondestructive. You don't have to first reselect all copies to make a change.

• The program only needs to store and compute one primitive for an array. No...

MagicaCSG Beta 0.5.3: Array Duplication

You are able to apply array/radial duplication to the following primitives in extrude/revolve/torus modes:

• Cube

• Sphere

• Cylinder

• Polygon

• 2D Triangle/Quad 

You can find the settings at the bottom of the stroke panel.

You may need to increase the volume resolution to improve the quality when you increase the arra...

MagicaCSG Feature: Radial Array Duplication

you can choose array or radial array for cube/sphere/cylinder/polygon/triangle shapes.

for radial arrays, you can adjust the repeat count and radius of the copies.

the resize gizmo still adjusts the size of each copy.

It only works for symmetric shapes.

MagicaCSG Feature: Array Duplication

In the next prototype/beta update, you'll be able to apply array duplication to the following primitives in extrude/revolve/torus modes:

• Cube

• Sphere

• Cylinder

• Polygon

• 2D Triangle/Quad

You'll be able to adjust array size and spacing (percentage of shape size).

Half/Bevel/Hole/... can also be applied to each primitive...

MagicaCSG Beta 0.5.2: Iso and Curved Cone Modes

Recent updates will focus on enhancing the features of existing primitive shapes.

This beta update adds two new modes to the cone property of extruded sdf shapes:

Iso Cone Mode

• allows you to create chamfer edges on top and bottom sides of basic primitives.

• Local Z Mirror is also supported.

• Note that Cone and Hole can be used together now (before only ...

MagicaCSG Feature: Curved Cone Mode

This new mode allows you to make the cone edges C1 smooth at top and bottom sides.

It can work with the new iso cone mode as well.

It's good for creating something like pumpkins or buttons, etc.

MagicaCSG Feature: Iso Cone Mode

New Iso Cone Mode allows you to create chamfer edges on top and bottom sides of basic primitives.

Local Z Mirror is also supported.

Note that Cone and Hole can be used together now (before only one can be enabled at one time).

It's good for creating hard surface objects.

MagicaCSG Demo: Text Outline

Bevel defines the inflating distance from the silhouette of texts, so it can be used to create outline effects.

Round is similar but will also round up the edges along z axis.

Torus mode can be used to create Neo signs. If the text is not in a separate object, then you need to use A/B material to assign an emissive material to the text primitives.

MagicaCSG Demo: 3D SDF Text

First Demo of the 3D SDF Text Tool!!!

The following features are demonstrated in this video:

• live updating text

• change width and height of characters

• change bevel and round of characters

• change torus mode

• boolean blending

This feature will be first updated in the prototype tier of this month.

MagicaCSG Beta 0.5.1: Avoid Blend

This update includes a new blend mode and some improvements for subgroups.

Avoid Blend Mode

a new blending mode besides Groove Blend.

This blend mode is basically a soft subtraction, followed by a hard union, but it avoids duplication of strokes and computations.

It can be applied to Union and Subtract Boolean operations (the difference is which object is softly subtracted.)

Inflate ...

MagicaCSG Progress: 3D SDF of Glyphs

A new prototype feature is under development: 3D SDF of Glyphs.

The new tool is able to convert the input text into sdf primitives that can be blended and boolean operated with other standard primitives. It also supports extrude and torus modes.

The algorithm is so far still brute force, so may not be efficient for scenes with lots of characters and curved edges (e.g., the character "@" includes around 40 bezier curves).

The alphabet is also limited to ...

MagicaCSG Feature: Avoid Blending

This update is already available for prototype users. The download link can be found in the last post.

Avoid Blend is a new blending mode besides Groove Blend.

This blend mode is basically a soft subtraction, followed by a hard union, but it avoids duplication of strokes and computations.

It can be applied to Union and Subtract Boolean operations (the difference is which object is softly subtracted.)

MagicaCSG Feature: Passthrough and Overridden Modes for Subgroup Boolean

There are two new properties for subgroups:

Passthrough

The default subgroup first blends the strokes locally within the group, and then blends the group with previous strokes.

Passthrough mode basically blends the strokes in the normal order as there is no subgroup there (while you can still operate the group of strokes as a compound object).

Overridden

Overridden mode overrides the contained strokes with the subgroup's o...

MagicaCSG Beta 0.5.0: Subgrouped Boolean

Subgroup

• You can group/ungroup the strokes via the stroke list menu.

• You can also group groups of strokes (up to 4 levels).

• Select/Transform/Duplicate/Delete/Hide a group will be applied to all the grouped strokes.

• The group has its own Boolean mode and blending options (blending factor, chamfer, opacity, etc.), which treats the grouped strokes as a compound stroke.

• Boolean operations within a group are localized...

Recent Progress

New Group Properties and Blending Modes

After the beta versions for the Subgroups, I'll begin to add more options for group properties and developed some new advanced blending options (e.g., Avoid mode in the image). Some of them are very useful, while some are very expensive and complicated.

These features will take some time and I may update them incrementally in the Prototype version before the stable Beta version. We may need a new interface for Blending as we...

MagicaCSG Feature: Collapsed Subgroups

These features have been updated for Prototype tier users (You can redownload the program).

• a quick update to fix a bug for subtract mode. [6/15]

There are some updates and bug fixes for the subgroup boolean to make it more convenient to use:

• Collapsed groups.

  You can click the arrows besides the subgroups in the list to close/open a subgroup.

  When a subgroup is not collapsed and ...

MagicaCSG Feature: New Dragging Method to Organize Multi-Level Subgroups

I developed a new dragging method in the stoke list to make organizing the subgroup hierarchy more convenient.

• You can move strokes around by pressing one of the selected strokes, and then drag and drop them to another location.

• You can move one or multiple strokes/groups all together, and they can belong to different groups or group levels.

• When dropping the strokes, you can determine at which group level you want to insert the moved strokes. (The...

MagicaCSG 0.4.5 Beta: Looped and Capped Splines

Some more spline modifiers in this update:

Looped Spline

clicked the "Loop" button on the top bar to make the first and last end points of a spline connected (supported in both continuous and discrete modes).

Capped Spline

Turn on "Curved Boundary" for "Cylinder" profile to enable this option.

The capped cylinder spline is basically a special case of el...

The Demo version is mainly for testing purposes and non-commercial usages, and it doesn't have the latest advance features.

You can check the system co...

MagicaCSG Demo: capped cylinder spline

Turn on "Curved Boundary" to enable this option.

The capped cylinder spline is basically a special case of ellipsoid sweep spline, which can be subtracted by other primitives with large blending factor or groove blending just like the sphere spline.

(cube, cylinder, hexagon, triangle sweep splines can only be "unioned" but not "subtracted" with large blending factor or groove blending)

It can be used for more flexible profile control than sphe...
