## What is Geometry Projection Camera?

This app is a camera-based drawing assistant that helps you create precise geometric drawings and artwork even without tools like rulers or compasses.  
By overlaying semi-transparent guides such as circles, regular polygons, and star shapes onto the live camera view, you can easily draw accurate figures just by tracing along the lines on paper.  
It is useful in many situations, including mathematics, art, crafts, illustration, manga, model making, and DIY.

＜Features＞  
・Three geometric modes  
Supports three modes: circle, regular N-gon (3–12 sides), and star (pentagram).  

・Fine control of side count  
Offers many options such as triangle, quadrilateral, pentagon, hexagon, octagon, decagon, and dodecagon.  

・Precise sizing with scaling  
Adjust the figure size from 30% to 100%, from small shapes to large ones as needed.  

・Perfect alignment  
Use the rotation slider to freely rotate the figure from 0° to 360° and project it onto the camera image at exactly the angle you want.  

・Six guide-line colors (semi-transparent for easy tracing)  
Choose the best color for your drawing background from six options: white, yellow, light blue (cyan), magenta, green, and black.  

＜How to use＞  
1. Select a shape mode  
Choose the shape that fits your purpose: circle, regular N-gon, or star.  

2. Adjust sides and size  
For regular N-gons, select from 3 to 12 sides, then adjust the figure size with the slider.  

3. Fine-tune the angle (non-circular shapes)  
Use the rotation slider to align the shape perfectly to the angle you want to draw.  

4. Choose a color  
Select the most visible guide-line color to match your drawing background.  

5. Draw along the camera guide  
Simply trace along the guide lines to complete your figure.  

With this app, you can create highly accurate geometric shapes even without traditional drawing tools.  

It is ideal for anyone who wants to draw precise geometric figures.
