Geometry buffer slice tool

A method of visualizing a three-dimensional volume for use in a virtual reality environment, comprising:

• uploading two-dimensional images for evaluation;
• creating planar depictions of the two-dimensional images;
• creating a voxel volume from the two-dimensional images;
• defining a slice plane to be used for slicing the voxel volume;
• determining whether the location of a current voxel is in front of or behind the slice plane, and if the current voxel is behind the slice plane, drawing the voxel, and if the current voxel is in front of the slice plane, not drawing the voxel.

A method of visualizing a three-dimensional volume for use in a virtual reality environment, comprising:

• uploading two-dimensional images for evaluation;
• creating a voxel volume based on the two-dimensional images;
• defining a slicing volume to be used for slicing the voxel volume;
• when the slicing volume is in contact with the voxel volume, send values representing all boundaries of the slicing volume to a geometry shader;
• if a current voxel in the voxel volume is within the boundaries of the slicing volume, drawing the voxel, and if the current voxel is outside of the boundaries of the slicing volume, not drawing the voxel.
