}
see this example, it prints out

i think this method only reads the headers of the source, and since most online radios use icycast/shoutcast, there arent any

if yes, wouldn't that be an unnecessary second network request which could use more internet traffic?

I set
.depthTestEnable = VK_FALSE,
.depthWriteEnable = VK_FALSE,
.depthCompareOp = VK_COMPARE_OP_LESS,
for
VkPipelineDepthStencilStateCreateInfo when configure graphics pipeline, but all standard Quick Items works badly if I use
z value as
z coordinate for vertices in my custom
QQuickItem with Vulkan RHI backend.
It looks they have variable
z coordinate across parent window viewport. In Renderdoc I see, that they even not write anything into z-buffer (but seems they depth-test it).

Hi. I have a Q3DScatter graph.
Its axis are configured this way:
m_graph->axisX()->setRange(-horizontalRange, horizontalRange);
m_graph->axisY()->setRange(-verticalRange, verticalRange);
m_graph->axisZ()->setRange(-horizontalRange, horizontalRange);
m_graph->axisX()->setSegmentCount(int(horizontalRange));
m_graph->axisY()->setSegmentCount(int(verticalRange));
m_graph->axisZ()->setSegmentCount(int(horizontalRange));
where horizontalRange and verticalRange are both 16.0f.
Now, I'm trying to move an item along a given trace. So for example, I'm trying to move an item along a circle. I define the circle using its parametric equations, that is x = rcost, y = rsint. everything is fine except that on horizontalPlane the trace is a perfect circle whereas on OXY (vertical) plane the trace is an ellypse. But its weird, given that this is a graph there has to be consistency between different axis. And yet, the coordinates on Y axis and the coordinates on X axis aren't consistent which results in an ellypse. Any idea why it is this way?
