Display processing method and apparatus

A display processing method, comprising:

• performing, by using a computer, a processing for adjusting positions of voxel data for an object and data of a geometric model for the object;
• calculating, by using the computer and for each voxel included in a range defined by a cross section among a plurality of voxels that are included in the voxel data, a voxel value of the voxel from weighted physical values that are obtained by weighting, for each of elements of the geometric model, a physical value that is set in the element, according to a length of a first vector obtained when projecting a second vector that is set for the element and represents a direction of an inner structure of the object onto the cross section, wherein the elements are included in a predetermined range of the voxel, and the cross section is set for the voxel data and the geometric model data;
• and
• rendering, by using the computer, an image by using the voxel value calculated for each voxel.
