目标：制作一张方形技术对比图，展示焦距如何改变简单 3D 房间场景中的透视效果，对比 Blender 渲染图与 GPT Images 2.5 的输出结果。 画布：方形图像，尺寸约为 1080 x 1080 px，带有细黑色外边框和两条水平黑色标题栏。该图包含 8 个渲染面板，排列为两个堆叠的 2 x 2 网格。 布局：上半部分在最顶部的黑色栏上居中显示加粗黄色文字 {argument name="top section label" default="Blender"}。下半部分在两个网格之间的黑色分隔栏上居中显示加粗黄色文字 {argument name="bottom section label" default="GPT Images 2.5"}。每个部分包含 4 个面板：左上角焦距 16，右上角焦距 24，左下角焦距 36，右下角焦距 50。在每个面板的右下角，放置加粗的白色焦距标签：“Focal length 16”、“Focal length 24”、“Focal length 36” 和 “Focal length 50”。 所有面板中重复的场景：一个简洁的极简主义 3D 测试房间，带有白墙、白色天花板、带有可见网格线的亮面浅灰色瓷砖地板，以及后墙上居中的深灰色垂直门或矩形面板。在场景中放置 3 个彩色立方体：前景中心放置 1 个大型亮面 {argument name="center cube color" default="red"} 立方体，中左侧放置 1 个小型亮面 {argument name="left cube color" default="blue"} 立方体，中右侧放置 1 个小型亮面 {argument name="right cube color" default="yellow"} 立方体。立方体在抛光地板上投射出柔和的倒影。使用向后墙汇聚的对称透视线。 面板特定的摄像机表现：在 Blender 部分，使焦距变化在视觉上保持准确：16 mm 呈现出非常广角的视觉效果，红色立方体显得更小且更远，房间空间感强，侧墙可见；24 mm 广角感稍弱，红色立方体变大；36 mm 变焦感更强，红色立方体突出；50 mm 变焦感最强，红色立方体非常大，侧面的立方体更靠近边缘。在 GPT Images 2.5 部分，展示相同的场景和相同的四个标签，但使 16 mm 和 24 mm 面板的广角程度低于预期，物体比例在不同焦距下的变化幅度较小；16 mm 面板不应像 Blender 的 16 mm 面板那样使物体显得过于缩小。 视觉风格：干净的合成 3D 渲染，柔和的全局光照，高调的白色房间，细腻的阴影和倒影，清晰的瓷砖地板，无人物，无额外物体，无水印。保持精确数量：2 个标注区域，8 个面板，每个区域 4 个焦距标签，每个面板 3 个立方体。

Goal: Create a square technical comparison graphic showing how focal length changes perspective in a simple 3D room scene, comparing Blender renders against GPT Images 2.5 outputs. Canvas: Square image, approximately 1080 x 1080 px, with thin black outer border and two horizontal black title bars. The graphic contains exactly 8 rendered panels arranged as two stacked 2 x 2 grids. Layout: The upper half is labeled {argument name="top section label" default="Blender"} in bold yellow text centered on a black bar at the very top. The lower half is labeled {argument name="bottom section label" default="GPT Images 2.5"} in bold yellow text centered on a black divider bar between the two grids. Each section contains exactly 4 panels: top-left focal length 16, top-right focal length 24, bottom-left focal length 36, bottom-right focal length 50. In every panel, place the focal-length label in bold white text at the lower-right corner: “Focal length 16”, “Focal length 24”, “Focal length 36”, and “Focal length 50”. Scene repeated in all panels: A clean minimalist 3D test room with white walls, white ceiling, glossy pale gray tiled floor with visible grid lines, and a rear wall with a centered dark gray vertical door or rectangular panel. Place exactly 3 colored cubes in the scene: 1 large glossy {argument name="center cube color" default="red"} cube in the foreground center, 1 small glossy {argument name="left cube color" default="blue"} cube to the mid-left, and 1 small glossy {argument name="right cube color" default="yellow"} cube to the mid-right. The cubes cast subtle soft reflections on the polished floor. Use symmetrical perspective lines converging toward the back wall. Panel-specific camera behavior: In the Blender section, make the focal length progression visually accurate: 16 mm appears very wide-angle with the red cube smaller and farther away, strong room expansion and visible side walls; 24 mm slightly less wide with the red cube larger; 36 mm more zoomed with the red cube prominent; 50 mm most zoomed with the red cube very large and the side cubes closer to the edges. In the GPT Images 2.5 section, show the same scene and same four labels, but make the 16 mm and 24 mm panels less wide than expected, with object scale changing only modestly across focal lengths; the 16 mm panel should not shrink the objects as much as the Blender 16 mm panel. Visual style: Clean synthetic 3D render, soft global illumination, high-key white room, subtle shadows and reflections, crisp tiled floor, no people, no extra objects, no watermark. Maintain exact count: 2 labeled sections, 8 panels, 4 focal-length labels per section, and 3 cubes per panel.
