Sparse Voxel Octree
Dec 29th
… is the latest data structure used by Carmack for his upcoming 3d engine. Here are some papers describing how octrees are implemented on the GPU (using pointers in the texture data 
), I’m currently reading this one. Brilliant stuff indeed.
This is the most similar technique to the one id is preparing.

Quick Problem
Dec 4th

This SDK post looks like a story written in C#-speak:
delivery1.Location = new Organization(“General Hospital”);
delivery1.TimeOfDelivery = new ApproximateDateTime(new ApproximateDate(2008, 11, 1), new ApproximateTime(00, 15, 35));
delivery1.LaborDuration = 123;….
delivery1.Baby = new Baby();
delivery1.Baby.Name = new Name(“Thomas John Andersen”);
delivery1.Baby.Gender = new CodableValue(“Male”, new CodedValue(“male”, “gender-types”, “wc”, “1″));
delivery1.Baby.Weight = new WeightValue(2.5, new DisplayValue(5.5, “pounds”));
delivery1.Baby.Length = new Length(0.46, new DisplayValue(18, “inches”));
delivery1.Baby.HeadCircumference = new Length(0.31, new DisplayValue(12.4, “inches”));
pregnancy.Delivery.Add(delivery1);
A strong-typed class library for all your life ! Brilliant !
Copy-Paste in Remote Desktop
