Information processing apparatus and information processing method for drawing image that reacts to input information

An information processing method of outputting image data where a particle is time-varied comprising:

• acquiring time-varying input information;
• generating, based on the input information, a field image in which a distribution of an attribute value for an attribute to be assigned to a particle is expressed in a two-dimensional space in which a particle exists for a predetermined timestep and storing the field image in a memory;
• and
• acquiring the attribute value of a particle from a field image read out from the memory based on a positional coordinate of the particle at a given timestep and rendering the particle at a subsequent timestep in accordance with the attribute value.

A computer program embedded in a computer readable medium, for outputting image data where a particle is time-varied, comprising modules of:

• acquiring time-varying input information;
• generating, based on the input information, a field image in which a distribution of an attribute value for an attribute to be assigned to a particle is expressed in a two-dimensional space in which a particle exists for a predetermined timestep and storing the field image in a memory;
• and
• acquiring the attribute value of a particle from a field image read out from the memory based on a positional coordinate of the particle at a given time step and rendering the particle at a subsequent timestep in accordance with the attribute value.
