Rails rendering instance variable from application.html.erb

由 落花浮王杯 提交于 2019-12-22 05:34:22
问题 I am following the Agile Web Development with Rails 4 book and I'm a bit confused on a part about rendering. The simple version of the question is... within the application.html.erb file there it says render @cart This is confusing because I thought that there needed to be a controller associated with that view in order to know which partial and @cart variable to use. Is it simply by naming convention that this line looks for a partial like _cart.html.erb? And in that case does it not

OpenGL: debugging “Single-pass Wireframe Rendering”

由 旧城冷巷雨未停 提交于 2019-12-21 20:45:11
问题 I'm trying to implement the paper "Single-Pass Wireframe Rendering", which seems pretty simple, but it's giving me what I'd expect as far as thick, dark values. The paper didn't give the exact code to figure out the altitudes, so I did it as I thought fit. The code should project the three vertices into viewport space, get their "altitudes" and send them to the fragment shader. The fragment shader determines the distance of the closest edge and generates an edgeIntensity. I'm not sure what I

问题 How can I use $this->renderView inside a symfony Command (not inside a controller)? I new about the function "renderView" but what do I have to setup to use it wihtin a command?
