Quickstart

• prerequisite

apt install libglfw3

• nuget package

• extension methods

using SearchAThing;

• controls xaml

xmlns:opengl="clr-namespace:SearchAThing;assembly=netcore-opengl"

• toolkit methods

using static SearchAThing.OpenGlToolkit;

• run examples

cd netcore-opengl
code .

hit F5 to start example ( change by edit .vscode/launch.json )

build

mkdir ~/opensource
git clone https://github.com/devel0/netcore-util.git
git clone https://github.com/devel0/netcore-sci.git
git clone https://github.com/devel0/netcore-opengl.git

cd netcore-opengl
dotnet build

👉 To make dependency netcore-util/netcore-sci debuggable comment PackageReference and uncomment ProjectReference for corresponding reference from csproj

Keynotes

• create a derived class from OpenGlModelBase:
  • OnInitialized can be used to init VertexArray and VertexBuffer objects for static data; compile shaders; retrieve attrib and uniform locations; define attrib pointers
  • Render can be used to draw frame
• create a derived class from OpenGlControl or use directly in xaml if not need to specialize
• glue Model to the control
• draw something using vertex manager ; it will rendered as coloured triangles
• set Debug in OpenGlModelOptions to get notified on console about GL error and break debugger in DEBUG mode

Examples

Triangle

0002

• OrthoFit

• GridSplitManager
