EvilSpirit 34a5d87011 Use relative chord tolerance instead of absolute. 
Commit 89eb208 has improved the overall situation with chord
tolerance, but it changed the display chord tolerance to use
an absolute value in millimeters as a stopgap measure.

This commit changes the display chord tolerance to be specified
in percents of entity bounding box instead of millimeters.
As a result, the linearized curves are both zoom level and sketch
scale independent.

In order to compute the bounding box, all entities are generated
twice. However, this shouldn't result in a noticeable slowdown,
since the bounding box calculation does not need the expensive
triangle mesh generation and the solver will converge immediately
on the second run.

Since the meaning of the preference has changed, a new name is
used (ChordTolerancePct instead of ChordTolerance), so that it
would be reset to the default value after updating SolveSpace.

The default value, 0.5%, was selected using trial and error by
judging whether cylinders of moderate dimensions were looking
aesthetically pleasing enough.

After this change, the only real function of the spacebar
shortcut is to reload imported groups, since manual regeneration
should not change anything anymore unless there is a bug.

README.md

SolveSpace

This repository contains the official repository of SolveSpace.

Installation

Mac OS X (>=10.6 64-bit), Debian (>=jessie) and Ubuntu (>=trusty)

Binary packages for Mac OS X and Debian derivatives are available via GitHub releases.

Other systems

See below.

Building on Linux

Building for Linux

You will need CMake, libpng, zlib, json-c, fontconfig, gtkmm 2.4, pangomm 1.4, OpenGL and OpenGL GLU. On a Debian derivative (e.g. Ubuntu) these can be installed with:

apt-get install libpng12-dev libjson-c-dev libfontconfig1-dev \
                libgtkmm-2.4-dev libpangomm-1.4-dev libgl-dev libglu-dev \
                libglew-dev cmake

After that, build SolveSpace as following:

mkdir cbuild
cd cbuild
cmake ..
make
sudo make install

A fully functional port to GTK3 is available, but not recommended for use due to bugs in this toolkit.

Building for Windows

You will need CMake, a Windows cross-compiler, and Wine with binfmt support. On a Debian derivative (e.g. Ubuntu) these can be installed with:

apt-get install cmake mingw-w64 wine-binfmt

Before building, check out the submodules:

git submodule update --init

After that, build 32-bit SolveSpace as following:

mkdir cbuild
cd cbuild
cmake -DCMAKE_TOOLCHAIN_FILE=../cmake/Toolchain-mingw32.cmake ..
make solvespace

Or, build 64-bit SolveSpace as following:

mkdir cbuild
cd cbuild
cmake -DCMAKE_TOOLCHAIN_FILE=../cmake/Toolchain-mingw64.cmake ..
make solvespace

The application is built as cbuild/src/solvespace.exe.

Space Navigator support will not be available.

Building on Mac OS X

You will need XCode tools, CMake and libpng. Assuming you use homebrew, these can be installed with:

brew install cmake libpng

XCode has to be installed via AppStore; it requires a free Apple ID.

After that, build SolveSpace as following:

mkdir cbuild
cd cbuild
cmake ..
make

The app bundle is built in cbuild/src/solvespace.app.

Building on Windows

You will need cmake and Visual C++.

GUI build

Check out the git submodules. Create a directory build in the source tree and point cmake-gui to the source tree and that directory. Press "Configure" and "Generate", then open build\solvespace.sln with Visual C++ and build it.

Command-line build

First, ensure that git and cl (the Visual C++ compiler driver) are in your %PATH%; the latter is usually done by invoking vcvarsall.bat from your Visual Studio install. Then, run the following in cmd or PowerShell:

git submodule update --init
mkdir build
cd build
cmake .. -G "NMake Makefiles"
nmake

MSVC build

It is also possible to build SolveSpace using MinGW, though Space Navigator support will be disabled.

First, ensure that git and gcc are in your $PATH. Then, run the following in bash:

git submodule update --init
mkdir build
cd build
cmake ..
make
