How do I upgrade to the latest version of Bixelangelo?


Bixelangelo features 3 modes:

1) Draw freehand

Press d, choose EDIT > Draw freehand, or click on the button in the WINDOW > Mode window.

Use your mouse to draw a sketch. Hold down the <Ctrl> key to draw straight lines.

2) Edit sketch

Press e or choose EDIT > Edit sketch, or click on the button in the WINDOW > Mode window.

Edit the sketch by clicking and dragging the points.

3) Edit roll

Press r or choose EDIT > Edit roll, or click on the button in the WINDOW > Mode window.

Edit the roll by clicking and dragging the roll control points.


Bixelangelo features 3 point types:

1) Move

A move moves to a new point without drawing a line or a curve: it starts a new path.

2) Line

A line draws a straight line from the previous point to the current point.

3) Curve

A curve draws a bezier curve from the previous point to the current point. Use the Bezier control points to change the shape of the curve.

When the path is closed, the last point is rendered inside the big circle of the first point.

The active point can be edited in the Point tool. Press <F7> or choose WINDOW > Point

Control points

Control points are not visible when you render your sketch in BluffTitler, but are used when editing to define the shape.

Bezier control points

The shape of the curves is defined by the 2 bezier control points. Select and move the bezier control points in edit sketch mode.

By deleting a bezier control point (right click with your mouse), the curve is turned into a straight line.


A point can have 2 bezier control points. Mark the Align checkbox in the point dialog(<F7>) to keep the 2 control points aligned.

Press a to toggle the alignment.

Roll control point

The angle of the roll is defined by the roll control point. When riding a roller coaster, the roll control point is on your right side.

Click and move the roll control point in the edit roll mode.

How to create a sketch

A sketch can be created in 4 ways:

1) Draw a sketch by hand

Press d to switch to Draw freehand mode. Left click your mouse button and draw your sketch. Hold down the <Ctrl> key to draw straight lines.

2) Build out of standard elements

Choose WINDOW > Element... to add a standard element to your sketch.

3) Open an EPS file

Choose FILE > Open... to open an EPS file.

The EPS file can also be dropped on Bixelangelo's window.

4) Trace a bitmap

Choose FILE > Trace bitmap... to trace a bitmap. This bitmap can be a PNG with a transparent background or a black shape on a non-transparent white background.

Bixelangelo features a built-in tracer. Alternatively you can use an external tracer.

How to edit a sketch

Press e or choose EDIT > Edit sketch to edit the curve and the bezier control points.

Select a point by left clicking on it.

Move the point by moving your mouse while holding down the left mouse button.

Press r or choose EDIT > Edit roll to edit the roll control points.

Right click on a point to delete it. When you right click on a bezier control point, the curve is turned into a straight line.

Richt click with the <Ctrl> key pressed to delete the line towards the point. This starts a new path at that point.

Connect paths by dropping a startpoint on an endpoint.

For more edit functionality see the keyboard and mouse sections.

How to view a sketch

Press <F1> to <F6> to select a default view.

If a point is selected, this point is used as the centre of view and centre of rotation.

Use the + and - keys on the numeric pad or your mouse wheel to zoom in/out

To move the camera: click on the background, keep holding down the left mouse button and move your mouse.

To rotate the camera: hold down the <Ctrl> key and move your mouse with the left or right mouse button pressed.

How to create a roller coaster


Choose WINDOWS > Element or press <F8> to display the element tool.

Select a standard element from the dropdown, set the properties and click on the Add button. This adds the selected element to the tip of your sketch.

Choose EDIT > Undo or press <Ctrl> + z to undo.

A typical roller coaster starts with a Lift hill followed by a Dive. This gives the cart energy to finish the track.


To smooth the transitions between the elements it's important to use a Smooth factor of at least 200 in the FILE > Save as... dialog.


Roll information is vital for roller coasters. Press r or choose EDIT > Edit roll to view/edit the roll. When riding the roller coaster, the roll control point is on your right side.

Make sure to mark the Roll checkbox in the FILE > Save as... dialog.


Bixelangelo features the following 14 standard elements:

Straight line

A straight line.

Lift hill

A lift hill, or chain lift is used at the start to give the cart enough energy to finish the ride.


A pre-drop, kicker, tester hill or trick hill is used right after a lift hill to relieve the stress of the chain or to fool the riders the dive has already started.


A dive is used after a lift hill to turn the potential energy into speed.


A simple hump.


A turn can be made more exciting by combining it with an elevation.

Circular loop

A loop shaped like a circle.

Immelmann turn

This does the same as the Circular loop, but only a half loop. It can be used as a fancy U-turn.

Clothoid loop

A clothoid loop has a lower radius at the top. This way it loses less speed than a circular loop.

Dive loop

A dive loop combines a loop with a turn.

Top hat

A top hat or top cap features a 90° ascent followed by a 90° descent.


A twist.

Cobra roll

A fancy U-turn that looks like the head of a cobra.


A U-turn that looks like the wings of a bat or butterfly.

Hammerhead turn

A U-turn often performed by planes.

Road straight

This does the same as the Straight line element, only it does not take over the slope (pitch) of the previous element.

Road bend

This does the same as the Turn element, only it does not take over the slope (pitch) of the previous element.

How to save your sketch

Choose FILE > Save as... to save your sketch.

Mark the Solid checkbox to create a filled shape for use in the vector layer

Non-solid shapes are used in the sketch layer.

Mark the Export roll checkbox to save the roll information. This is important for roller coasters.

To save your sketch as a standard, compatible EPS file for use in other apps, do not export roll and make sure it's 2D.

BluffTitler Templates

To get you started, Bixelangelo generates BluffTitler show files. Templates are offered for:

  • spinning logo

EPS files

Bixelangelo opens and stores it sketches in the EPS format.

The EPS format is a huge format and Bixelangelo only supports a small subset: the outlines of uncompressed, unoptimized EPS files. But of course, all EPS files saved by Bixelangelo can be opened by Bixelangelo and BluffTitler!

Options dialog

Choose SETTINGS > Options... to open the options dialog.

Pen size

The thickness of the lines.

Point size

The radius of the (control) points.

Grid size

Points are snapped to this gridsize.

Display size

This can be used to correct a bad behaving video driver.

When you use a Windows display setting of 125% or higher and there's an offset between where you click and where the new point appears, first try updating your video driver. If this does not help, set the Bixelangelo display size to the same value as the Windows display size. In this example to 125%.

The neutral value is 100%.

Show help texts

External tracer

Bixelangelo features a built-in tracer. Alternatively you can use an external tracer. In the current version only Potrace is supported. To use Potrace, click on the Browse button and select potrace.exe.

Leave this option blank to use the built-in tracer.
