Patent ID: 8149236

Claim:
An information processing apparatus, comprising: a slice information group storage portion in which a slice information group having multiple pieces of slice information is stored, the slice information being information constituted based on two-dimensional image data obtained as a result of extraction with multiple planes from 3D voxel information, which is volume texture of a three-dimensional object, and being constituted by information of multiple points having positional information, which is information indicating position, and elasticity information, which is information of elasticity; a slice information group output portion that outputs the slice information group; an instruction receiving portion that receives an instruction for a given point or region in the slice information group that has been output; a positional information acquiring portion that acquirers at least one piece of positional information of the point, or a point constituting the region, corresponding to the instruction; an elasticity information acquiring portion that acquires at least one piece of elasticity information paired with the at least one piece of positional information that has been acquired by the positional information acquiring portion; and an elasticity information output portion that performs output based on the at least one piece of elasticity information that has been acquired by the elasticity information acquiring portion, wherein when the instruction receiving portion receives an instruction for a internal point or internal region of the three-dimensional object: the positional information acquiring portion acquirers at least one piece of positional information of the internal point, or at least one point constituting the internal region of the three-dimensional object, corresponding to the instruction, and the elasticity information output portion performs output based on the at least one piece of elasticity information of the internal point, or the point constituting the internal region of the three-dimensional object.
