Filed: 1996-07-10
Abstract: PROBLEM TO BE SOLVED: To provide a joining structure which can join together a pair of partition walls without increasing the number of sorts of partition walls. SOLUTION: The first side face 31 of a connecting member 30 is joined with the end face of a partitioning panel 20 of a partition wall 2A, and the end face of the partitioning panel 20 of another partition wall 2B is contacted with the second side face 32 coupled with the first side face 31 at a prescribed angle excluding a right angle, followed by locating with respect to the partition wall 2A and jointing with the second side face 32. Thereby a pair of partition walls 2A and 2B can be joined together simply with good precision at the prescribed angle, and because this allows the use of any existing partitioning panel 20, the number of sorts of partitioning walls 2A and 2B will never increase.

IPC: G06T11/20
Filed: 1993-07-22
Abstract: PURPOSE:To set apparent texture patterns to be constant without depending on the inclination of a vector. CONSTITUTION:When the texture patterns are plotted at corresponding inclination angles, texture patterns which apparently become the same texture patterns are stored in texture pattern memories 12-1 to 12-n corresponding to respective inclination angles as data.

The n 1 selector 14 inputs angle information showing the inclination angle of the vector from an SEL terminal and selects one enable signal. Since the enable signal is that showing the texture pattern deformed in accordance with the inclination angle of the vector, it is prevented that the apparent texture pattern changes in accordance with the inclination angle of the vector.
