我想将urdf或sdf模型用于无限平面以建模Bullet Physic。我尝试设置大数字来调整盒子几何尺寸,但它会崩溃,也许是引擎中的数字溢出。见代码:
<?xml version="0.0" ?>
<robot name="infinity_plane">
<link name="planeLink">
<contact>
<lateral_friction value="1"/>
</contact>
<inertial>
<origin rpy="0 0 0" xyz="0 0 0"/>
<mass value=".0"/>
<inertia ixx="0" ixy="0" ixz="0" iyy="0" iyz="0" izz="0"/>
</inertial>
<collision>
<origin rpy="0 0 0" xyz="0 0 -5"/>
<geometry>
<box size="3000000000000000 3000000000000000 10"/>
</geometry>
</collision>
</link>
</robot>
我可以做一些box size = "inf inf 10"
吗?
