vector v_array[] = { 1, 2, 3}; // an_array[] == { {1, 1, 1}, {2, 2, 2}, {3, 3, 3} } //The array() function creates an array from its arguments. int i_array[] = array(1, 2, 3, 4, 5); //You can use array() to generate an array of any type. To forc...
@orient = quaternion(m); 常用矩阵有两种,一种是全能的四阶方阵(a 4x4 array of numbers),能对物体进行旋转/缩放/移动/倾斜/透视调整这些操作,在vex中被称为matrix。还有一种少一行一列的三阶方阵,只能用于处理旋转和缩放,在vex中写做matrix3。 第一行代码创建了一个叫做m的matrix3变量,并且用ident()函数...
如果这个球是个polygon sphere那显然没啥问题,因为球上每个点的位置确定了,它的姿态自然也就跟着旋转了,点面的所在位置直接影响它的外观。可是我们这是个primitive sphere,它就像一个大粒子(a big standalone particle),所以并没有外表面的点给它旋转(there's no 'outer skin' of points to rotate)。 如果这是...
首先,贴出vex可用的函数列表,版本16.5:https://www.sidefx.com/docs/houdini/vex/functions/index.html 如需其他版本可到http://www.sidefx.com/docs/自行查找 其实这些直接在houdini帮助文档中查看是一样的,而且帮助文档还能下载案例文件 并且把光标放在函数名上,按F1就能直接调出该函数的帮助文档 我在后期也许...
Making a VR action game from start to finish with a team of 3 is more than challenging! However, with the power of Houdini, Vex, Python and some imagination, it's entirely possible. In this talk, Maria will share handy tips and tricks for improving many aspects of virtual reality game ...
WRANGLING A TEAM REQUIRES MORE THAN VEX Artist to Leader is a talk from Hudson Martins Head of FX in Axis Studios. It is aimed towards artists and supervisors alike. Hudson is planning to share his knowledge and experience adapting from being a Houdini generalist artist and to managing a team...
Functions can be defined inside of a function (nested functions). 函数可以在函数(嵌套函数)中定义。 Main(context) function 主函数 A VEX program must contain one function whose return type is the name of the context. This is the main function of the program that is called by mantra. The co...
VEX in Houdini. We will start with basic attributes in VEX to variables then moving to loops and its types such as for, while and do while and foreach loop which is specially used for arrays. Discussing nested loops is also a very important part of this course. We will learn how to ...
用法:foreach ([element_type] value; array) {} 条件语句foreach,就是把每个array计算一遍,合起来到左边的量那里。 这个+=的是 a+=b 等价于 a+b。这里sumOfArray的值从0加了11。 执行效果: for 用法: 创建attributewrangle 这里引进一个chi函数,chi函数你要到外部追加 ...
